**fd1d_heat_explicit_test**,
a FORTRAN90 code which
calls fd1d_heat_explicit(), which
solves the time-dependent 1D heat equation, using the finite difference
method in space, and an explicit version of the method of lines to handle
integration in time.

fd1d_heat_explicit, a FORTRAN90 code which uses the finite difference method (FDM) and explicit time stepping to solve the time dependent heat equation in 1D.

- fd1d_heat_explicit_test.f90, a sample calling code.
- fd1d_heat_explicit_test.sh, runs all the tests.
- fd1d_heat_explicit_test.txt, the output file.

**TEST01** runs with initial condition 50 everywhere, boundary conditions
of 90 on the left and 70 on the right, and no right hand side source term.

- plot_test01.png, a PNG image of the solution, using the MATLAB MESH command to emphasize the method of lines approach underlying the solution.
- h_test01.txt, the computed H data.
- t_test01.txt, the T data.
- x_test01.txt, the X data.
