open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi everyone,

I am running telemac2d, and I am releasing drogues in the mesh. I have an error


|runCode: Fail to run

I arrived to the conclusion that this is due to a drogue moving out of the grid. I tried to add the BORD.f file from the tests cases to my fortran file, but I still get the error. Maybe I have to change something in the .cli? The conditions apply to tracers and no to drogues.

Any ideas?

Hello

This is not obvious as concusion. First you have to run the model without drogues, if everithing is OK, you add the drogues and if the run crushes, then you have to run in a debug mode (add the keyword DEBUFFER=1) and see where it crashes.

This will indicate where the proble could be. These are fierst step of debugging. You have to do further before concluding that drogues are going out of border.

with my kind regards

Thank's for the answer.

I already ran it several times without the drogues without any problem. I tried to run it with several drogue release configurations. Everytime, if I look at the trajectories of the drogues from the temp file, there is always a drogue which is very close to an open boundary, and moving towards it. So I'm pretty sure it comes from that.

I'll try the debuffer mode, and I'll tell you what I get.
