open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,

I make a river flow simulation. To calibrate the simulation, I want to change the bottom friction in some parts of the area. I changed the bottom fricition with Blue Kenue in the geometry file. When I started the simulation by using a previous computation file, telemac uses the bottom friction of the previous computation file and not of the geometry file, although in the listing printout telemac writes that the bottom friction is taken from geometry file.

I have also the probelm, that I can't change the bottom friction with Blue Kenue directy in the results file to use it as previous computation file.

Can somebody help me?

Best regards.

Hi

If you delete the friction coefficient in the result, Telemac will use the friction coefficient of the geometry file.
In fact, there is a priority, first geometry and after previous computation if friction exists.

hope this helps
