Mesher options

Lateral and longitudinal discretization

lat_step

long_step

nb_pts_lat

--constant_long_disc

mesh_crue10_run.py has the optional argument --floodplain_step to specify elements size if "casiers" are meshed.

Constraint lines

--constraint_lines

--interp_constraint_lines

Planar projection of cross-sections

--project_straight_line

Note : mesh_mascaret_run.py do not provide this option because cross-sections are built orthogonal to hydraulic axis.
