Dear all,
I'm trying to solve a system of PDE, where the highest order is 4. COMSOL supports finite elements of 5th order. So solving the equation system should be possible by using COMSOL. But the result is zero.
Boundary conditions may be a concern, as high-order PDE generally require more boundary conditions. In my case, I imposed two homogeneous Dirichlet conditions for the dependent variable (scalar) and it's divergence. These two conditions have corresponding physical meanings.
Does anybody have an idea about such a problem? I appreciate your suggestions!
