With certain values of mesh (e.g. 20 cells/wavelength) the mesher fails to create a mesh, and the results window shows the error below. How do I compile a defect report for this?

error message:

I've recently seen such a "segmentation violation" in other cases but during the simulation, not during the mesh making. The best thing is if you can share the design file (+ layers) with your local Agilent EEsof support department. There is a new unified engine in ADS2003C, and it's likely related to that change. They can also show you how to turn on the old engine as a workaround.

I got the same problem in RFDE 2004a. Is there any update information about this issue? What should I look for?

Segmentation violation just means that the module crashes. It does not imply that it is crashing in the same part of the code or for the same reason. Therefore, the best thing to do is to send in the model files required for us to reproduce and fix the problem and also to determine an effective workaround.

I've pass the problem by layout in segments.
