fem1d_adaptive, a FORTRAN77 code which applies the finite element method to a linear two point boundary value problem in one spatial dimension, using adaptive refinement to estimate the error, refine the mesh, and produce an improved solution.

fem1d_adaptive is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version.
fem1d, a FORTRAN77 program which applies the finite element method to a linear two point boundary value problem in a 1D region.
FEM1D_BVP_LINEAR, a FORTRAN77 program which applies the finite element method, with piecewise linear elements, to a two point boundary value problem in one spatial dimension.
FEM1D_NONLINEAR, a FORTRAN77 program which applies the finite element method to a nonlinear two point boundary value problem in a 1D region.
FEM1D_PMETHOD, a FORTRAN77 program which applies the p-method version of the finite element method to a linear two point boundary value problem in a 1D region.
FEM1D_PROJECT, a FORTRAN77 program which projects data into a finite element space, including the least squares approximation of data, or the projection of a finite element solution from one mesh to another.
FEM1D_SAMPLE, a FORTRAN77 program which samples a scalar or vector finite element function of one variable, defined by FEM files, returning interpolated values at the sample points.
