Strange Meshing Error with Stitched Surface
Altair EmployeeI am trying to simulate WiFi signal propagation inside a stitched surface using RL-GO but am receiving the following vague errors:
(Error 17179: The mesher encountered a problem.
Error 16561: Mesher aborted - General error.
Error 17580: The mesher aborted abnormally while meshing PlaneShell.)
when I try to mesh the structure. 'PlaneShell' is the only component giving the error at this point and is a stitched composite of several surfaces imported from SolidWorks. Interestingly the model will mesh if I scale it down to 0.2 size (the the user-defined variable 'scale') but not if it is unscaled (i.e., setting 'scale' to 1). Additionally, I recently updated from FEKO 7.0 to FEKO 14.0. In FEKO 7.0, I had no issues meshing scaled or unscaled models. I've attached the model.
Would anyone have suggestions for eliminating this error? I must use RL-GO. Also, does Altair keep a listing of FEKO errors with explanations anywhere? Such a list would make the software far more user-friendly and would eliminate a lot of searching through and waiting for answers from forums.

Hi @riiily,
I've played with your model and got it to mesh:
Steps:
- Copied the original geometry out of the stitched part;
- Used the 'Repair' tools on the primitive objects to change their internal representations and tweak the tolerances
- Stitched the parts together again with a tolerance of '0.1'
I'm not sure why it stopped working between versions. It might just be that there was a library upgrade that affected the way a tolerance influenced the model's validity when you meshed. For now, you should be able to continue working anyway.
Kind regards,
Andries
PS: I used CADFEKO 14.0.432-293039 (x64) from 2016-12-06
