I have created a nonconforming mesh( with hanging node) in .msh format using Matlab. I need to solve the Laplace equation with homogeneous Dirichlet boundary conditions using CG/DG method. I can import this mesh into Freefem. I used the usual weak formulation of the Laplace equation, but Freefem does not compute the exact solution.
My question is, does FreeFEM++ solves any PDE on meshes with hanging nodes? If yes, how to treat these hanging nodes?
