Icon Diffpack consists of a collection of object-oriented libraries (implemented in C++) for solving partial differential equations with a particular focus on finite element methods, and several Unix utilities for general software management and numerical programming. In particular, this piece of software is aimed at rapid prototyping of simulators based on PDEs, still offering a high level of efficiency.

User Comments:

  • "Diffpack looks like one of the best implementations of a numerical package in C++ that I have seen.", J. H., Chicago, IL, USA
  • "One of the things I find most impressive and unusual about Diffpack is the fact that it is well documented.", T. K. O., RPI, NY, USA
  • "I just browsed your wonderful package Diffpack. Many researchers can avoid rebuilding the wheels. Your generous contributions to the scientific world is deeply appreciated.", C.-C. C., University of Arizona, Tucson, AZ, USA
