open TELEMAC-MASCARET The mathematically superior suite of solvers

Dear helpful all,

I have what I thought would be a rather simple task but am not finding any solutions to it that I can understand (my fortran skills are very limited).

I want to impose boundary conditions varying along the boundary, but constant in time. I have wave height, mean direction and frequency at the black circles and would like to put this information into my model - either interpolating between them or just splitting the boundary in two different parts would be enough in this case (the waves just change at one point - 3 values are the same and the other 2 are the same).

I've been reading the many different posts about spatially and temporally varying boundary condtitions and trying to understand the limwac routine from the Manche example without much success. Then again they are all dealing with temporal variations too so I'm hoping there's a more simple solution to my problem. I'm coupling this with a telemac2d and the boundary is a tidal boundary with TPXO data (just in case it matters) that I need to add the waves onto.

I'm afraid I have no idea how to change the limwac subroutine, although I have found the part that needs to be modified. So I gave up and started a new topic in the hope that someone would explain this in a way an idiot can understand.

Just want to say that I am no longer waiting for a reply to this bad question. I would delete it if I could but since I can't find that option I just want to apologize for the stupid post. I guess I was feeling hopeless and desperate yesterday.

I'm getting closer to understanding the solutions already given and will post more specific problems in more appropriate threads if I run into them.
