1// libCEED + MFEM Example: BP3
2//
3// This example illustrates a simple usage of libCEED with the MFEM (mfem.org)
4// finite element library.
5//
6// The example reads a mesh from a file and solves a linear system with a
7// diffusion stiffness matrix (with a prescribed analytic solution, provided by
8// the function 'solution'). The diffusion matrix is expressed as a new class,
