**fem1d_bvp_linear_test**,
a FORTRAN90 code which
calls fem1d_bvp_linear(), which
applies the finite element method, with piecewise linear elements,
to a two point boundary value problem in one spatial dimension,
and compares the computed and exact solutions
with the L2 and seminorm errors.

fem1d_bvp_linear, a FORTRAN90 code which applies the finite element method (FEM), with piecewise linear elements, to a two point boundary value problem (BVP) in one spatial dimension, and compares the computed and exact solutions with the L2 and seminorm errors.

- fem1d_bvp_linear_test.f90, a sample calling code.
- fem1d_bvp_linear_test.sh, runs all the tests.
- fem1d_bvp_linear_test.txt, the output file.

One of the tests makes convergence plots in the H1, L2 and Max norms.
