PseudoPack 2000 Edition Manual - Solution of PDEs using pseudospectral (collocation) methods. Parallel Multi-domain Decomposition - Parallel Fortran 90 module to solve positive-definite elliptic linear second-order operator systems. Parallel Hierarchical Adaptive MultiLevel Project (PHAML) - Fortran 90 code using adaptive refinement, multigrid and parallel computing to solve 2-D linear elliptic PDEs. Successor to MGGHAT. FD - Fortran 77 package by Jiri Zahradnik for 2-D P-SV elastic second-order finite differences. ELLPACK - High level, portable system for solving elliptic boundary value problems, implemented in Fortran 77. [Commercial] FUN2D/3D - Describes a Fortran 95 code for solving the Navier-Stokes equation on a fully unstructured grid. Boundary Element Method - Fortran 77 codes to solve the Laplace and Helmoltz equations. PARAMESH - Package of Fortran 90 subroutines designed to provide an application developer with an easy route to extend an existing serial code which uses a logically cartesian structured mesh into a parallel code with adaptive mesh refinement (AMR).
