FEM2D_POISSON_SPARSE_LAKE is available in a C++ version and a FORTRAN90 version and a MATLAB version.
FEM2D_POISSON_SPARSE, a C++ program which solves a 2D Poisson problem, using a sparse matrix solver, and user input.
FEM2D_POISSON_SPARSE_BAFFLE, a C++ library which defines the geometry of a rectangle channel containing 13 hexagonal baffles, as well as boundary conditions for a given Poisson problem, and is called by fem2d_poisson_sparse as part of a solution procedure.
FEM2D_POISSON_SPARSE_ELL, a C++ library which defines the geometry of an L-shaped region, as well as boundary conditions for a given Poisson problem, and is called by fem2d_poisson_sparse as part of a solution procedure.
