Hi,
I was trying to run an impedance calculation on a square copper coil in air. I am using a trial version of comsol. It gives me the following error:
Failed to evaluate variable
variable: mod1.emw.ahPortx
Geometry: 1
Boundary: 33
failure to evaluate expression
expression ((((mod1.emw.ahPortx*mod1.tEx)+ (mode1.tEy*mod1.emw.ahPorty))+(mod1.emw.ahPortz*mod1.tEz))/mod1.emw.wPort)
