Setting bathymetry on edges
d-flow fm bathymetry

Based on prior work with a different modeling platform, we have sometimes found it useful to set bathymetry directly on the faces (aka edges, velocity points), rather than at cell centers or nodes.

After stepping through the code, I was able to do this to some extent (not fully tested yet) by adding a section to my old-style external forcing file with "QUANTITY=bedlevel". Since this option is not mentioned in the manual (i.e. table B.1 in the user manual), I am wondering if this is ill-advised, and whether that option is likely to remain in the code for the foreseeable future.

Thank you --
