Mesh Generation

    The mesh is generate with the pre-processor MATISSE, from sinusx file (sx). The mesh will be an unstructured one.


Bathymetry

    The bathymetry is interpolated from a matrix of point : debord.sx :

here the bathymetry viewing with RUBENS post-processor:

    Had lines are defined to ensure that unstructured mesh will follow those lines (main angle of the bathymetry).
 


Mesh

    Two differents criterion of refinement are defined in order to refined minor bed and progressively extend the cell in order to have precision and not to have too much cells for calculation.(MATISSE gives an estimation of the number of nodes). Then MATISSE generate the mesh.

Zoom on minor bed area :


Number of cells : 23239
Number of nodes : 11703
