Suppose we want to solve the two dimensional equation :

Model equation

The exact solution of this equation is given by :

e^{2t}sin(x+y)cosh(x+y).

We could use two maps of isosurfaces: one for the calculated solution, another for the exact solution. We will also generate a plot of the grid nodes, with the initial conditions. The initial and the four boundary conditions are chosen to be the exact solution.
