Hi, I am trying to model in the AC/DC module and at the very end when I try to plot the volume impedance density versus frequency for my base electrode, I get the error of " division by zero". Is this because of the sharp angles? I have tried different meshing but I still get the same error. That said, I get this error only for the base of my model which looks like a box and not the other parts.
The second question is that, how can I define phase angle in COMSOL and then plot it versus frequency.
Thanks in advance for your help.
