PDE coefficient form, can coefficients be variable dependent?

Please login with a confirmed email address before reporting spam

Hello,
I would like to solve an equation with the PDE interface in Comsol 4.2a. I use coefficient form and wonder if the coefficients can be dependent on the same varaible the equation is solving for?

So, if the equation is solving for phi, can I put any of the coefficients to be a function of phi in order to catch for example a quadratic behaviour not represented by any term in the given equation form?

best regards,
Mattias
