Find the zero of a function

Please login with a confirmed email address before reporting spam

Hello,

I am new to COMSOL and working on a 3D model in the AD/DC module. Is there a way to find the coordinates at which the electric potential is null?

Thanks Claudia

Hi Claudia,

if it is about visualizing, you can apply a filter in the respective plot, such as V>Vmin && V<Vmax. Vmin and Vmax are defining an interval around zero.

Cheers Edgar

...or do an isosurface plot at V=0.
