fem2d_sample, a FORTRAN90 code which evaluates a finite element function of a 2D argument.
The current version of the code 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.
FEM_IO, a FORTRAN90 code which reads or writes node, element and data files defining a finite element model.
FEM_TO_TEC, a MATLAB code which converts FEM models into TEC graphics files.
FEM1D_SAMPLE, a FORTRAN90 code 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, text files that describe a 2D finite element geometry and associated nodal values;
FEM2D_HEAT, a FORTRAN90 code which solves the 2D time dependent heat equation on the unit square.
FEM2D_PACK, a FORTRAN90 code which contains utilities for 2D finite element calculations.
FEM3D_SAMPLE, a FORTRAN90 code which samples a finite element function of three variables, returning interpolated values at the sample points.
HISTOGRAM_DATA_2D_SAMPLE, a FORTRAN90 code 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.
MESH_BANDWIDTH, a FORTRAN90 code which returns the geometric bandwidth associated with a mesh of elements of any order and in a space of arbitrary dimension.
