FEM2D_PACK, a MATLAB library which contains utilities for implementing the finite element method.
The emphasis is on simplicity and clarity. Only the 2D case is handled, with a choice of low order triangular and quadrilateral elements.
A few routines are included for computing a "sphere grid", that is, a finite element mesh on the surface of a sphere.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
FEM2D_PACK is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
FEM_BASIS, a MATLAB library which can define and evaluate basis functions for any degree in an M-dimensional simplex (1D interval, 2D triangle, 3D tetrahedron, and higher dimensional generalizations.)
FEM_IO, a MATLAB library which reads or writes the node, element and data files that define a finite element model.
FEM1D_PACK, a MATLAB library which contains utilities for 1D finite element calculations.
FEM2D, a data directory which contains examples of 2D FEM files, text files that describe a 2D finite element geometry and associated nodal values;
FEM2D_HEAT, a MATLAB program which solves the time dependent heat equation in the unit square.
FEM2D_POISSON, a MATLAB program which solves Poisson's equation on a square, using the finite element method.
FEM2D_POISSON_RECTANGLE_LINEAR, a MATLAB program which solves the 2D Poisson equation on a rectangle, using the finite element method, and piecewise linear triangular elements.
FEM2D_SAMPLE, a MATLAB library which evaluates a finite element function defined on an order 3 or order 6 triangulation.
FEM3D_PACK, a MATLAB library which contains utilities for 3D finite element calculations.
