| - | The spatial discretization | + | In the code Sunfluidh, the spatial discretization |
| + | 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_doc| Meshgen]]**__. | ||
| + | <note important> | ||
| + | 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, ...) | ||
