Mesh generator for sunfluidh

In the code Sunfluidh, the spatial discretization of equations is carried out on a cartesian staggered grid.
When the grid is regular (cell size is identical over the computational domain), the code build the mesh itself. The user can also build a non-regular grid for sunfluidh by using the in-house software Meshgen.

More regular is the mesh more accurate is the simulation. Several basic rules should be respected so far as it is permitted. The cell size ratio between two adjoined cells does not generally overcome 5\%, especially in the strong gradient areas. For every cell, the aspect ratio should be : This rule can be relaxed in some peculiar cases (weak gradient area, close-wall area, …)
