In fact there is no exercice their. It is just some kind of model 
(non-physical) problem that can be solved by ff3d.

> What means "on" and "in" ?
- "on" says that
and     v=sin(pi*x)*sin(pi*y)*sin(pi*z)
are verified by u and v "on" the boundary "dO" of the domain "O"
- "in" says that
and     v-Laplacian(v)+u=g
are verified inside the domain "O" (almost everywhere in "O")

Does this answer your question?
