A 2D Poisson Problem in an L-shaped Region

FEM2D_POISSON_ELL is a FORTRAN library which defines the geometry of an L-shaped region and other data needed in order to execute the FEM2D_POISSON program.

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.
