Some solvers may require a minimum degree of knowledge of the structure of the matrix. To make an example when solving a mixed u-p problem, it is important to identify the row associated to v and p. another example is the automatic prescription of rotation null-space for smoothed-aggregation solvers which require knowledge on the spatial position of the nodes associated to a given dof. This function tells if the solver requires such data
