    Non-destructive testing (NDT) team at the Solid State Physics Department of the Faculty of Applied Physics and Mathematics cooperates on the broad scale with industry representatives in developing methodology and apparatus for magnetic NDT.



    Currently we are optimizing Pipeline Inspection Gauge (PIG) with Magnetic Flux Leakage (MFL) system to evaluate technical condition of pipelines. Such system consists of magnetizing yoke and magnetic field sensors. Working PIG can reach velocity of even 10 m/s due to liquid media pressure. Our job is to model effect of velocity on eddy currents generation and hence distortion of MFL signal.

    We have heard about the EMWorks software as a result of searching for Finite Element Modelling (FEM) software which would be adequate for our purposes. After the review of various offers we stated that EMS has all features we need. The great advantage of this package is that it is based on SolidWorks. Thanks to this design of even very complex models becomes child's play. My first magnetostatic model in EMS was created in just a few minuts! I highly recommend EMWorks software for all those who need friendly interface as well as professional FEM software.

    Our design will revolve around the analysis of a new electron catcher (Faraday cup) and design an Electron Catcher for target station EMS from EMWorks has been a valuable tool for integrating electromagnetic component design into our SolidWorks environment.

    EMS has allowed us to simplify the development stages for RF and high power AC componentry by reducing the number of experiments required during prototyping. The intuitive user interface combined with the simple transition between the design environment and finite element suite ensure that any required changes to a design can be completed, implemented, and brought back into the EMS environment for further simulation in a very short timeline.

    Thank you for your valuable tool and help

    I used EMWorks for an undergraduate biomedical engineering project. I am thankful that EMWorks is very well integrated with SolidWorks, which makes constructing 3D geometries straight-forward. The step-by-step tutorial of EMWorks also helped me in learning the software. Many other multiphysics software applications don't have easy-to-use tutorials. Overall, EMWorks has been helpful software for my project.

    I got used to EMS very fast. I just needed two days to get a first result. Especially the simplicity to apply boundary conditions or to refine the mesh at certain surfaces or solids is great! And also the options to plot the results are very nice and intuitive. In the end the results of the simulation matched very well with the experimental values.

    I used EMS to teach the third year undergraduate course "Finite Element Methods for Mechatronic Systems Engineering". Students were already familiar with and SOLIDWORKS Simulation and Electromagnetics; they had no troubles learning EMS and working on meaningful assignment problems all within one lab. The use of EMS definitely added value to the course and enhanced students' learning experience.

    EMS is quite useful program for finding electric and magnetic fields in unorthodoxly shaped assemblies. It has been especially helpful for me when I was trying to design circuits with high voltage and current applications, which are potentially lethal for students. EMS comes with a set of tutorials that guide users through the model setup and demonstrate a large variety of applications. Overall, a very professional electromagnetic simulation software.

    My First impression of HFWorks right out of the gate was, “ Brilliant”. Having HFWorks integrated directly into SolidWorks saves me so much time when it comes to building and testing coaxial RF connectors. I was very impressed with one click I was able to obtain TDR results of my RF model which really gives me everything I am looking for, especially when other software like HFSS makes it such a pain to get similar results.

    The EMS magnetostatics module has been amazing for designing permanent magnet configurations to optimize magnetic field shape. The interface with SolidWorks is really intuitive and I was able to start using it quickly. Even better, the customer service and tech support have been wonderful! I highly recommend this software.

    I used EMS software for the induction heating analysis of a gear. The transient magnetic analysis helped me obtain good simulation results which corroborate what is mentioned in the literature.

    The software has a user-friendly interface. Moreover, The EMS license comes with a set of pre-defined tutorials and Demo Viewer examples to guide the users and help them get familiar with the software. I had a good experience with EMS. The induction heating examples that are available in EMS Demo Viewer helped me learn more about EMS.

    It is a powerful simulation tool that I would recommend to anyone who is doing projects on induction heating.

    EMWorks has been tremendously helpful in my journey to design my brushless motor prototype. MotorWizard was the main tool that I used in the design process. It felt intuitive and relatively easy to navigate. The integration inside SOLIDWORKS is seamless! Once the stator is designed, it is very easy to create a 3D model. Overall, I am very pleased and thankful for all the support that I received from EMWorks team. The motor has been tested and the results are accurate. It works just as expected. 



    I would strongly recommend MotorWizard solution to my colleagues and professors!

    Over the past year, I’ve had the opportunity to use EMWorks to aid in my study of magnetic coils on our apparatus. With this tool, we can model many types of coil designs, such as using thin magnet wire, and water cooling it, or instead going with hollow-core type of wiring (with finite diameters and realistic spiraling modeled in SW) and running cool water through that. We can then see our magnetic field profiles all around the coils, and of course in the center of our Helmholtz configuration, where we would like to ensure very flat magnetic fields. In a complex environment such as a cold-atom experiment, I want to ensure that the vacuum chamber geometry itself would not impede our ability to ramp up and down the current on the magnetic coils, due to eddy currents. By tuning the materials, and in real-time designing components the way they would be engineered, we will be able to fine-tune our apparatus to our needs and constraints. In the future, we will continue to evaluate the eddy currents present in our system as we try different parameters for our magnetic field control (see image).

    One great aspect to continue expanding on would be the video tutorials highlighting the many ways to get students started on using EMWorks for their applications. As a beginner, setting up the basic parameters like the “air geometry” was made simpler by watching someone show those steps specifically through SolidWorks.

What is Electrostatic Analysis? And what is used for?

Electrostatic is the branch of science that deals with the phenomena arising from stationary and/or slow-moving electric charges. Electrostatic approximation rests on the assumption that the electric field is irrotational, i.e. the curl of the electric field is null. From Faraday's law, this assumption implies the absence or near-absence of time-varying magnetic fields, i.e. the derivative of the magnetic field with respect to time is also null. In other words, electrostatics does not require the absence of magnetic fields or electric currents. Rather, if magnetic fields or electric currents do exist, they must not change with time, or in the worst-case, they must change with time only very slowly. In some problems, both electrostatics and magnetostatics may be required for accurate predictions, but the coupling between the two can still be ignored.

The EMS/Electrostatic module is primarily used for computing electric potential and electric field due to charges and voltages in insulators and conductors.It has many practical applications, including:

• High Voltage Components
• Insulating Systems
• EMC Compatibility

• Transformers
• Electronic tubes
• Capacitors

What is Electric Conduction Analysis? And what is used for?

Electric Conduction is, in essence, based on the electrostatic approximation. Unlike the Electrostatic analysis which deals with insulators and electric conductors, the Electric Conduction deals with only conducting media which can sustain a current flow.

The EMS/ Electric Conduction module is primarily used for computing current flow in conductors due voltage differences. . It has many practical applications, including:

• Resistors

What is Magnetostatic Analysis? And what is used for?

Magnetostatics is the study of static magnetic fields. In electrostatics, the charges are stationary, whereas here, the currents are steady or dc(direct current). As it turns out magnetostatics is a good approximation even when the currents are not static as long as the currents do not alternate rapidly. Furthermore, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.

In EMS/ Magnetostatic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Ampère's law, i.e. the curl of the magnetic field is equal to the static electric current density, are invoked to compute the magnetic field and its related quantities due to electric currents and permanent magnets. It has many practical applications, including:

• Motors and generators
• Linear and rotational actuators
• Relays
• MEMS
• Magnetic recording heads
• Magnetic levitation
• Solenoids
• Loud speakers
• Electromagnetic Brakes and Clutches
• Magnetic bearings
• MRI
• Sensors

What is AC Magnetic Analysis? And what is used for?

AC, or alternating current, Magnetic, is the study of magnetic fields due to alternating, or time harmonic, currents. Similar to Magnetostatic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.

In EMS/AC Magnetic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Faraday's law,, i.e. the induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit, are invoked to compute the magnetic field and its related quantities due to alternating electric currents and voltages. It has many practical applications, including:

• AC Motors and generators
• Sensors
• Coils and transformers
• Inverters
• Converters
• Bus bars
• Inductors
• NDT and NDE
• Inductive heating and hardening

What is Transient Magnetic Analysis? And what is used for?

Transient Magnetic, is the study of magnetic fields due to time varying currents, typically caused by surges in currents. Similar to Magnetostatic and AC Magnetic, Maxwell's displacement current that couples the electric and magnetic fields is assumed to be null.

In EMS/ Transient Magnetic analysis, the Gauss's law for magnetism, i.e. divergence of magnetic flux density is null, and Faraday's law,, i.e. the induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit, are invoked to compute the magnetic field and its related quantities due to permanent magnets and time varying electric currents and voltages. It has many practical applications, including:

Can you give me some examples of design issues that EMS/Electrostatic module can address?

The Electrostatic module can help study a large number of devices and address numerous insulating and conducting phenomena. Below is just a partial list:

• Avoid rapid reduction in the resistance of an electrical insulator, that can lead to a spark jumping around or through the insulator, i.e. dielectric breakdown. This phenomenon is common in high voltage and high power applications.
• Avoid the ionization of a fluid surrounding a conductor, i.e. corona effect, in some applications such as power transmission equipments, transformers, capacitors, electric motors and generators.
• Produce corona in some other applications such as the manufacturing of ozone, scrubbing particles from air in applications such as air-conditioning systems, in nitrogen laser, when removing the unwanted electric charges from the surface of aircraft in flight, and in electrostatic copying.
• Assure that a high voltage machine is properly grounded.
• Reduce the electrostatic discharge in PCB and electronic designs.

Can you give me some examples of design issues that EMS/Magnetostatic module can address?

The Magnetostatic module can help study a large number of devices and address numerous magnetic and electromechanical phenomena. Below is just a partial list:

• Avoid saturation in magnetic devices. Magnetic saturation is a limitation occurring in ferromagnetic cores. Initially, as current is increased the flux increases in proportion to it. At some point, however, further increases in current lead to progressively smaller increases in flux. Eventually, the core can make no further contribution to flux growth and any increase thereafter is limited to that provided by air - perhaps three orders of magnitude smaller.
• Minimize the cogging torque. The cogging torque of electrical motors is the torque due to the interaction between the permanent magnets and the stator slots of a Permanent Magnet (PM) machine. Also termed as detent or 'no-current' torque, it is an undesirable component for the operation of such a motor. It is especially prominent at lower speeds, with the symptom of jerkiness.

• Study the trade-off between soft magnetic and hard magnetic materials in terms of magnetization and demagnetization.
• Study the effect of B-H curves or magnetization curves on the performance of magnetic devices and circuits.
• Optimize the torque in motors while maintaining the driving current to a minimum.
• Avoid sparking and thus minimizing brush wear and electric noise in motors, solenoids, actuators, and other electromechanical devices.
• Optimize the force for linear solenoids and the torque for rotary solenoids without overheating the winding.
• Assure the proper Lorentz force in a speaker voice coil.
• Evaluate complex coil structures.
• Evaluate a multitude of permanent magnet configurations.

The Transient Magnetic module can help study a large number of devices and address numerous magnetic, eddy current, and transient effects. Below is just a partial list:

• Take into account both eddy current and saturation in devices that use time varying magnetic fields such as loudspeakers and induction machines.
• Optimize the Non-Destructive Testing (NDT) and Non-Destructive Evaluation (NDE) sensors to detect deep flaws and cracks.
• Study time varying devices such as magnetic heads, pulsed power transformers, and electromagnetic launchers.

HFWorks for medium to high frequencies, i.e. few hundred MHz to few hundred GHz, applications such as antennas, connectors, filters, etc.
However, there could be an overlap. If you are not sure, please contact our specialists to help you better choose the suitable package for you.

Do I need Solidworks or Autodesk Inventor to run your software?

Yes.

Up to what frequency can I use EMS? how about HFWorks?

EMS is typically used for DC to about 500 MHz. HFWorks is generally used for frequencies ranging from few hundred MHz to around 200 GHz. There are overlapping frequencies between EMS and HFWorks. Please contact us to discuss your needs and which product is more suitable for your application.

I accidently changed my SolidWorks model, what happens to my results?

To protect your work from accidental changes, we recommend that use the Study Locking feature in both EMS and HFWorks. A locked study may be viewed but cannot be edited or changed. Of course, you can always unlock the study if you need to make changes.

I need to make a minor change to my study, do I need to redo things from scratch?

No. You simply clone the original study, i.e. make a copy of it, and make the necessary changes in the cloned study. A cloned study inherits all features of the original study, i.e. study properties, materials, boundary conditions, excitations, mesh, etc.

Yes. Depending on the study type, there are various symmetry boundary conditions.

What is Low/High Frequency Electromagnetics?

There are two major sub-domains in electromagnetics: low-frequency and high-frequency domains. Both domains are governed by Maxwell's equations.
The low-frequency domain includes the major part of the electromagnetic devices such as bushing, insulators, circuit breakers, power generators, transformers, electric motors, capacitors, magnetic levitation devices, synchronous machines, DC machines, permanent magnet motors, actuators, solenoids, etc.
Strictly speaking, any application in which displacement currents are negligible can be classified as low-frequency. The absence of the displacement currents de-couples the electric and magnetic fields and the situation becomes static.
Typically, frequencies from DC to a few hundred MHz are considered low!
The high-frequency domain includes the study of electromagnetic waves and the propagation of energy through matter. It may be sometimes difficult to distinguish between high-frequency and low-frequency. Nevertheless, we can generally say that electromagnetic fields in which the displacement currents cannot be neglected belong to the high-frequency domain. The displacement currents couple the electric and magnetic fields to each other and the situation becomes fully dynamic. Examples of devices that use high-frequency include antennas, waveguides, transmission lines, filters, couplers, dielectric resonators, etc.
Typically, frequencies from a few hundred MHz to a few hundred GHZ are considered high!

Do I Need EMS or HFWorks for my electronic device?

• If a shield uses steel where the saturation is a concern.
• To study power integrity, power supply, power management, and battery management.
• To compute capacitance, inductance, and resistance.
• To study the skin and proximity effects.
• If motion is involved.

Whereas HFWorks shall be used in the following situations:
• If the device is comparable or larger than the wavelength.
• For frequencies: from few hundred MHz to few hundred GHz.
• To calculate the radiation and far-fields.
• To compute S-parameters, e.g.insertion loss and return loss.
• To compute impedance and signal propagation.
• To compute the TDR.
• To study crosstalk and distortion.
• To study signal integrity.
• To compute the heat due to dielectric and conductor losses.
• To study resonance behaviour and compute quality factors.

Yes. No conflict exists between the two license managers because each one of them is a stand-alone license manager. They are completely separate.

Can I get more accurate results if I reduce the iterative solver residual error?

You may get slightly more accurate results if you reduce the default value. However, it will take longer for the matrix solver to converge. It is recommended that you don't change it.

I do not have Solidworks or Autodesk Inventor. Do I need to purchase it separately? or does the software come with it?

No, the software does not come with Solidworks nor Autodesk Inventor. To purchase a license of Solidworks or Autodesk Inventor, please contact your local Solidworks or Autodesk Reseller.

What is S-parameters Analysis? And what is used for?

Scattering parameters or S-parameters (the elements of a scattering matrix or S-matrix) describe the electrical behaviours of linear electrical networks when undergoing various steady state stimuli by electrical signals. Although applicable at any frequency, S-parameters are mostly used for networks operating at radio frequency and microwave frequencies where signal power and energy considerations are more easily quantified than currents and voltages. S-parameters change with the frequency are readily represented in matrix form and obey the rules of matrix algebra.

The HFWorks/S-parameters analysis belongs to the high frequency electromagnetic, or the full wave, regime, i.e. Maxwell's displacement current that couples the electric and magnetic fields is significant and thus taken into consideration. The vector wave equation, i.e. combination of the full Maxwell's equations, is solved using vector finite element to obtain the S-parameters and the electric/magnetic fields and related design parameters. It has many practical applications, including:

• Connectors
• Filters
• Couplers

What is Antenna Analysis? And what is used for?

An antenna is a transducer that transmits or receives electromagnetic waves. In other words, antennas convert electromagnetic radiation into electric current, or vice versa.

Antennas are used in systems such as radio and television broadcasting, point-to-point radio communication, wireless LAN, cell phones, radar, and spacecraft communication.

Using HFWorks/Antenna analysis, antennas of all types and shapes can readily be simulated.

• Printed
• Horn

What is Resonance Analysis? And what is used for?

Resonance is the tendency of a system to oscillate with larger amplitude at some frequencies than at others. These are known as the system's resonant frequencies. At these frequencies, even small periodic driving forces can produce large amplitude oscillations, because the system stores energy. When loss is small, the resonant frequency is approximately equal to a natural frequency of the system, which is a frequency of unforced vibrations. Some systems have multiple, distinct, resonant frequencies. Resonance phenomena occur with all types of waves: there is mechanical resonance, acoustic resonance, electromagnetic resonance, nuclear magnetic resonance, electron spin resonance and resonance of quantum wave functions.

In HFWorks/Resonance analysis, we are concerned only with electromagnetic resonance. The vector wave equation, i.e. combination of the full Maxwell's equations, is solved using vector finite element to obtain the natural resonant frequencies and their corresponding electric/magnetic field distributions. It has many practical applications, including:

• Dielectric resonators
