Detailed Description

Laplacian (Poisson) problem.

The laplace equation is solved on a regular mesh of the unit square, and is compared to the analytical solution.

This program is used to check that getfem++ is working. This is also a good example of use of GetFEM. This program does not use the model bricks intentionally in order to serve as an example of solving a pde directly with the assembly procedures.
