MGGHAT MGGHAT (MultiGrid Galerkin Hierarchical Adaptive Triangles) is a FORTRAN program for the solution of general second order linear self-adjoint elliptic partial differential equations with Dirichlet, natural or mixed boundary conditions on 2D polygonal domains (possibly with holes). MGGHAT uses a finite element method with linear, quadratic or cubic elements (user selectable) over triangles. The adaptive refinement via newest vertex bisection and the multigrid iteration are both based on a hierarchical basis formulation. Run time and a posteriori graphical displays are made with gnuplot.
