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 along any direction does not generally exceed 5%, especially in the strong gradient areas.
- For every cell, the aspect ratio should be :
$$0.2 \le \frac {\Delta x_j}{\Delta X_i} \le 5$$
This rule can be relaxed in some peculiar cases (weak gradient area, close-wall area, …)
