Hi,
I'm running EMPro 2015.01 and I've been running into this same problem on a few different simulations. They're all FEM simulations where I get the following error while:
Mesh boundary is overlapping, the pairs of overlapping triangles can be found in design_mesh_overlaps.sat.
I've tried excluding various models from the mesh until the simulation will run, and then manually re-creating the geometries that are causing the error, but no luck. I've tried looking at the design_mesh_overlaps.sat file, but the information in it is not meaningful to me.
I've attached an image of one of the simulations which is a right-angle SMA connector (waveguide port, 1W modal source) on a PCB (lumped port, 50ohm voltage source).
Any idea what is causing this and how to fix it?
Thanks,
Chris
Is this an imported object? Most of the time, when an object is imported from a CAD file, the mechanical tool used to create the file doesn't produce a "clean" enough model for electrical simulation. You may have better luck redrawing it in EMPro using your model as a guideline.
Try looking at the failed geometry in the advanced visualization window, under the results tab. From there, go to tools, then object statistics. Sometimes you will find valuable information in there.
In addition, I believe you should be using the same voltage source for your waveguide port. The 1W modal source is useful for modeling actual waveguide, but less so when there is a specific impedance associated with the port. There should be clarification of when to use and when to not use modal ports in the next release, but I think this case, a voltage port would be more appropriate.
