Not necesarilly - another solution is to use getfem::interpolator_on_mesh_fem
This structure has a function eval which interpolates the solution and
its gradient.
The code could approximately look like:
----------------------------------------------------------------------
getfem::mesh_fem femT;
std::vector<bgeot::scalar_type> T;
/*
...
setup femT and the rest of the problem, solve it and then
extract the DOFs value into vector T.
...
*/
getfem::base_vector sol; // interpolated solution at probePoint
getfem::base_matrix grad; // iterpolated solution gradient
getfem::base_node probePoint;
/*
...
set up coordinates of the probePoit */
...
*/
getfem::interpolator_on_mesh_fem itpr(femT, T);
itpr.eval(probePoint, sol, grad);
