FEMLISP

A Common Lisp framework for finite element methods

FEMLISP is a framework for solving partial differential equations with the help of the finite element method (FEM). It is written completely in Common Lisp.

Functionality:

Interactive environment
Unstructured meshes in arbitrary space dimensions
Cells are arbitrary products of simplices
Automatic triangulation of 2D domains (interface to Triangle)
Lagrange finite elements of arbitrary order
Isoparametric and non-parametric cell mappings
Error estimators and adaptive mesh refinement strategies
Interfaces to direct solvers (SuperLU and UMFPACK)
Geometric and algebraic multigrid methods
Equations (diffusion-convection-reaction)
Systems (elasticity, incompressible flow)
Nonlinear problems
Eigenvalue problems
Time-dependent problems
Integrated graphics (interfaces to OpenDX and Gnuplot)
Integrated documentation, demonstrations, and tests
Very liberal license (modified BSD)
