special_20	Hello all, I would like to create a mesh where the bathymetry Zf is defined as a function of X and Y. For example : Zf(X,Y) = 10+(X+Y)^2. Is it possible to do so ? Regards

Hi,

I know this is not the answer you expect but what I usually do in this kind of situation is to load an XY text file (columns X and Y) to python and using a Pandas Dataframe I add (using a function or similar) the third column (Pandas has numpy heavy lifting in the background so it has a decent performance) and then save it to a XYZ text file to later use in BlueKenue.

Maybe there is a procedure using telemac's fotran files but i'm not really confident in my FORTRAN skills.

regards,

José Díaz.

Hi,

You can do it rather easily in BlueKenue, just define your base mesh with your set of (X,Y) coordinates and use Tools->Calculator to compute a new object based on the mesh's coordinates, see screenshot below.

It's also something that fudaa can do very easily.

For the fortran alternative, you can use the subroutine CORFON, have a look at the bumpflu validation case for example.

Best regards
PL

special_20	Thank you for your answers ! In particular, the answer about Blue Kenue is what I was expecting for but I didn't find it in by my self... I made my mesh and what I did is modifying the corfon subroutine to get what I wanted. Regards
