open TELEMAC-MASCARET The mathematically superior suite of solvers

Hello,

I am writing for assistance with the attached error. I have read posts related to this error, but I am wondering if there is another option besides reducing the time step. I am trying to run this simulation on a cluster using 100 nodes (20 cores, 5 nodes each).

Any advice would be greatly appreciated.

Thank you,
Taylor

Hello Taylor,

How many triangles do you have in your 2D mesh and how many horizontal planes do you use?

As you may have read, with this error message, the first thing to try is to reduce the time step, but perhaps investigation should be done if there is an issue not solved (big local velocities e.g. in shallow waters).

Hope this helps,
