Hi, Wolfgang,
I have included it actually, and also the distributed/grid_refinement.h was
also included. Because I want to import the outside mesh to build up the
triangulation, I also used Gridin to work on the triangulation, which is
like as the following:
void CoupledTH<dim>::make_grid_and_dofs() {
GridIn<dim> gridin; // instantiate a gridinput
gridin.attach_triangulation(triangulation);
std::ifstream f("inputfiles/mesh.msh");
gridin.read_msh(f);
...
I am not sure if this impacts the declaration.
Thank you very much.
Best,
Xiang
