FEM2D_POISSON_SPARSE_ELL
A 2D Poisson Problem in an L-shaped Region


FEM2D_POISSON_SPARSE_ELL is a C++ library which sets up the geometry and data for a Poisson problem in an L-shaped region for solution by FEM2D_POISSON_SPARSE.

This mesh, which uses 65 nodes, was created by starting with a crude mesh, and having it refined by TRIANGULATION_REFINE and renumbered by TRIANGULATION_RCM.
