Clean CAD, Better EM Simulation: The hidden Link Between Clean Geometry and Reliable EM Results
|
|
|
In electromagnetic (EM) simulations, the biggest sources of error often aren’t in the physics — they stem from your CAD geometry.
Imperfections like gaps, overlaps, and unnecessary details in your 3D model can lead to distorted EM field results, solver crashes,
and excessive computation times.
In part 1, we explore why clean, precise geometry is a crucial yet frequently
overlooked factor for achieving high simulation accuracy, optimized performance, and trusted EM results.

Clean CAD, Better EM Simulation: Common CAD Geometry Issues That Sabotage Your Simulation
|
|
|
|
The importance of clean and correct geometry in FEA simulation is discussed in the first part of our blog series.
As we saw, not all simulation errors come from the solver—many originate from hidden flaws in your CAD geometry.
Tiny gaps, overlapping solids, unnecessary fillets, and zero-thickness surfaces are just a few of the issues that
can quietly compromise simulation accuracy long before the first field is calculated.
In Part 2, we explore the most common CAD geometry mistakes that lead to inaccurate or failed EM simulations—and
how to identify and fix them early in your workflow

Customer Testimonial
|
I am writing this testimonial to express my satisfaction with the EMS add-on for Inventor. [..]
The first aspect that struck me about EMS is its integration with Autodesk Inventor.
[...] One of the standout features of EMS is its ability to accurately simulate and analyze magnetic fields.
The software's advanced algorithms and intuitive interface made it easy for me to set up complex simulations and
obtain insightful results.[...] The customer support provided by the Academic Team has also been exemplary.
