Hi All,
I am trying to move all parallel triangulation nodes by a constant
displacement, but that breaks the periodic face pairs match when I
call GridTools::collect_periodic_faces(...). I use the following code for
the mesh movement. The dftPtr->triangulation has periodicity constraints
using add_periodicity(...).
std::vector<bool> vertex_moved(dftPtr->triangulation.n_vertices(), false);
const std::vector<bool> locally_owned_vertices =
GridTools::get_locally_owned_vertices(dftPtr->triangulation);
for (typename DoFHandler<C_DIM>::active_cell_iterator
cell=d_dofHandlerForce.begin_active(); cell!=d_dofHandlerForce.end();
++cell){
if (cell->is_locally_owned())
{
for (unsigned int vertex_no=0;
vertex_no<GeometryInfo<C_DIM>::vertices_per_cell;
++vertex_no)
{
const unsigned global_vertex_no = cell->vertex_index(vertex_no);
if (vertex_moved[global_vertex_no]
|| !locally_owned_vertices[global_vertex_no])
continue;
Point<C_DIM> vertexDisplacement; vertexDisplacement[0]=1e-4;
vertexDisplacement[1]=0; vertexDisplacement[2]=0;
cell->vertex(vertex_no) += vertexDisplacement;
vertex_moved[global_vertex_no] = true;
}
}
}
dftPtr->triangulation.communicate_locally_moved_vertices(locally_owned_vertices);
}
Any ideas if I am doing anything wrong? Thanks in advance.
Best,
Sambit
