open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello

I am running my simulation using Telemac 3D however I have got an error related to the maximum interaction.

Could you please help me to sort it out this problem? I already have changed the time steps and the solver accuracy plenty of times. I am adding my geo file, steering file and the .cli file.


Thanks

Joel

Hello,

This is not very clear because the problem appears at a time step that is not asked in the listing, so we see only the maximum of iterations reached (programmed to be printed even if not asked to warn the user).

So you should first set : LISTING PRINTOUT PERIOD = 1

to have more data on the step that causes the problem. Another possibility is to tune the compiler so that it gives the traceback and the very line where the first NaN occurs (not recommended for current runs because it slows down a lot but efficient for bug tracking).

With best regards,
