While doing a charge simulation of a simple rectangular structure of Si with Al contacts on both sides and assigned as contacts in the electrical conditions UI, and the simulation region contain part of the contacts inside, the following error is received:

“No contacts were found in the simulation region”

Please note it is a 3D simulation.

Attached is a screenshot.


Thanks for the help.

Hi. Do you have the right mesh order on the rectangles? I can see that you also have a rectangle for air. If the contacts overlap with some other geometry then check if the mesh order is forcing the other material to occupy the volume of the metal contacts. To learn about mesh orders please see this page (mesh order DEVICE).
