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.

We are going to use MGEN to design the domain, mesh it, put the initial and boundary conditions, and assign the equation to the mesh. Once done this, we can return to the main simulation panel, and press continue.
