◆ setVertexDofs()

MoFEMErrorCode MoFEM::FieldBlas::setVertexDofs ( FieldBlas::VertexCoordsFunction  lambda,
const std::string  field_name,
Range *  verts = nullptr 
)

Set DOFs on vertices using user functionExample:

auto do_something = [&](VectorAdaptor &field_data, double *x,
double *y, double *z) {
field_data[0] = (*x);
field_data[1] = (*y);
field_data[2] = (*z);
};
CHKERR m_field.getInterface<FieldBlas>()->setVertexDofs(set_distance,
"DISP");
Note
Function works both ways, using it coordinates can be set from field.
Parameters
lambdafunction evaluating field at points
field_nameis a field name
vertspointer to vertices if null all vertices in the field are evaluated)
