I used Comsol to solve a PDE problem. I know that the solution is stored in the object fem.sol.u and the unstructured mesh points are stored in fem.mesh.p.

Then, if i see the size of fem.sol.u i find a column vector of length M, while the fem.mesh.p is a 2 columns vector ( x and y coordinates of points in wich field is calculated ) of length N, shorter than the solution one !!!.
Could anyone tell me how to do?
Thanks.

Just an idea: Try to extend the mesh first with fem.xmesh=meshextend(fem) and see if the extended mesh fits the size of your solution.
