Hello,

I have been trying to simulate an IR photodetector in DGTD mode. After setting up the simulation I have been failing to run the simulation due to a meshing error. The error is described as "tilki(process 0): The program terminated due to an error: Edge meshing failed with Netgen exception: No edge seems to contain the three points!
tilki(process 0): Error: there was an unknown parallel error. The error code is 9000, the process number is 0" (Don't mind the server name tilki(process 0):)

The structure consists of 3D rectangles lined up to observe the absorption. A plane wave source and EM field monitor is present and the whole structure is the sim region. I have tried different meshing orders, disabling a 2D rectangle in the geometry to be sure it was not the problem, but Im still facing the same problem. I can provide additional details if need be.

Thanks to anyone that replies to help.

Hi Arda,

I apologize for the late reply. This error looks a bit unusual to me. Typically we see mesh fails with curved surfaces. But you using rectangular objects only. Would you be able to share a screen shot of the "Mesh" tab of DGTD? Also, what is the size of the simulation domain in each direction? Are any of the rectangular objects/features extremely small compared to the overall simulation domain? A screenshot of the geometry might also help.

Regards,
Amrita
