Re: [Getfem-users] smoothed nodal gradient

[Yves Renard]

Dear Wen,

The convex numbering depend only on the mesh, so it is the same, yes. However, the dof numbering in a P0 discontinuous fem is not the same as the numbering of convexes. The correspondance is given by the mesh_fem object.

Dear Yves,

Thanks and I agree it will not be difficult. I think we could compute the gradient on a discontinuous fem with p-1 order and then use convex_to_point to get the corresponding elements attached to a node. The convex_to_point returns a container of the convex in the mesh structure and my question is that is the order(numbering) of convex in the mesh the same as the one in continuous fem and the discontinuous fem suppose they are defined on the same mesh? Thanks.

Regards,

Wen

Dear Wen,

No this function is not available in Getfem. It would not be very difficult to do of course.

Subject: [Getfem-users] smoothed nodal gradient




Dear all,


With linear elements, the gradients are discontinuous from element to element. Is there any way in getfem that we can obtain a smoothed gradient at each node which is basically the average of gradients of the elements connected to that node? Thanks in advance.

Regards,
Wen
