Calculating Resistance without the AC/DC module

Please login with a confirmed email address before reporting spam

Hi, I am working on a problem where I am simulating this 2D metal sheet with various shapes cutout throughout it which changes it's resistance. When I was using the trial version that included the AC/DC module it was easy to calculate the resistance. I would run 10 amps through one side with the terminal boundary condition and then use global evaluation and ec2.R11 to find the overall resistance of the metal foil. However, in the full version, I currently do not have the AC/DC module (yet at least) and also need to calculate the resistance. I can use the electric potential boundary condition to set a voltage instead of using the terminal boundary condition. However, after the simulation runs I have not been able to find a way of calculating the resistance of the metal foil. Is it possible to do this calculation without the AC/DC module or would it be required?

Hi Alexander,

I am not sure if the basic module has the normal current density available. If yes, you can integrate it across the potential boundary to get the total current.

OR write it out in terms of components.
