FEM2D_SAMPLE, a C++ program which evaluates a finite element function of a 2D argument.
The current version of the program can only handle finite element meshes which are made of piecewise linear triangles of order 3 or 6.

FEM2D_SAMPLE is available in a C++ version and a FORTRAN90 version and a MATLAB version.
FEM1D_SAMPLE, a C++ program which samples a scalar or vector finite element function of one variable, defined by FEM files, returning interpolated values at the sample points.
FEM2D, a data directory which contains examples of 2D FEM files, three text files that describe a 2D finite element geometry;
FEM2D_HEAT, a C++ program which solves the time dependent heat equation in the unit square.
FEM2D_PACK, a C++ library which includes utitlies for 2D finite element calculations.
fem2d_poisson_rectangle_linear, a C++ program which solves the 2D Poisson equation on a rectangle, using the finite element method, and piecewise linear triangular elements.
FEM2D_PROJECT, a C++ program which projects a function F(X,Y) into a given finite element space of piecewise linear triangular elements.
FEM3D_SAMPLE, a C++ program which evaluates a finite element function defined on 3D tetrahedral mesh.
HISTOGRAM_DATA_2D_SAMPLE, a C++ program which demonstrates how to construct a Probability Density Function (PDF) from a frequency table over a 2D domain, and then to use that PDF to create new samples.
