Change the governing equation

Please login with a confirmed email address before reporting spam

Hello everyone,

I am a newbie with comsol I'm currently studying the piezotronic effect on ZnO MR in comsol and I need help with equation setting. In my simulation, I would like to change the governing equation, but I don't know how to edit it. Is it possible to change the governing equation in comsol, and how to change it?

Hi Hue,

Activate the Equation View in the Show More Options window. You can then adjust and modify the expressions that define variables and equations for the physics nodes in the Equation View subnodes that become available. Note that by doing so you are no longer solving the exact equations that the physics interface would solve if unchanged.

Best regards,

Magnus
