Simulate Fields Outside of Semiconductor Device
Is it possible to simulate the electric fields outside a solid-state device (such as a PN junction)? In other words, I'd like to create a boundary outside the device representing air and solve...

Good afternoon, I'm going to make a simulation where I need to export to a file. DAT (or .TXT), eight points for monitoring of temperatures, plus the time step. How to do this? I can only export only...
View ArticleHow to export deformed structure from COMSOL?
I simulated a MEMS module based structure in COMSOL. I obtained the deformed structure after doing the simulation. I want to export the deformed structure so that it can be used for further analysis in...
