Hi there,
Recently I use PDE weak form for energy minimizing problem. But instead of minimizing it, comsol gave me the result of maximizing the equation. How can I actually the minimize it instead of maximizing it ?

PS: I know I need to ensure the second derivative of function positive in order to get the minimum result. But how can I implement this condition to comsol?

Thank you so much.
