open TELEMAC-MASCARET The mathematically superior suite of solvers

hi,all
I have to modify the flow field with a prescibed folwrates boundary,and a tidal level boundary with TPXO database.But my listing file shows EXCEEDING MAXIMUM ITERATIONS all the time.I don't know why.Can you help me?

Hello,

Your case immediately crashes for some reason, so just try to run only a few time steps with output periods set to 1 or 2 instead of 360 to see what happens, for example look at initial conditions to see if they are continuous and smooth, and check that the first boundary conditions given at boundary are compatible with this initial condition. Try to see where you may have large velocities in the mesh, that could show where the problem is.

Also add :

SOLVER : 1

in your steering file, default value is 3 and 1=conjugate gradient will be more efficient in your case.

With best regards,

Thanks very much. I have done what you said,and I have add SOLVER =1 in my cas file. And the listing file shows that my boundary haven't flux. If my boundary setup has problem? Can you help me to find my error?
