FEM1D_ADAPTIVE
Finite Element Method with Adaptive Refinement


FEM1D_ADAPTIVE is a FORTRAN90 program 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.
