Description

It is often beneficial for mechanical problems to have a grid with the same interpolation as the displacement field. This is usually "just" a change in order of the required interpolation. The simplest hack here would be to just create a dof handler and use the nodal dofs to generate the new nodes of the grid. It should be noted that at the time of writing this (~v0.4.0) we rely on Lagrange-type interpolations for the grid to make the dof management functional.

Contributor guide

Research direction
Study the existing grid interpolation code and the DOF handler implementation to understand how to modify the interpolation order. Then implement a method to generate new grid nodes from nodal DOFs.
