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...

Natural Convection in a Box

Hi, I'm trying to get that cats eye picture of natural convection in a box. My solution converges but I dont see any streamlines. If someone can spot a mistake that I made, it would be helpful. I am...

8 points of monitoring the temperatures - how to export to a dat file in one...

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...

How 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...

Which interface choose for fluid flow with heat transfer

Good day! I would like to ask for an advice. I wish to solve the following problem: I have a plate of a solid material with low thermal conductivity. There is a pipe with cold water inside the plate....
