Hello NEKs,
in the last day I had a couple of problems with my runs, so I started
again the turbChannel example on our machine to get a better feeling for
the parameters. When I run the turbChannel example, the run stopped
after 5172 time steps with an 'emergency exit' cause the CFL number is
getting to high. Do you know from where does this occur?? I just added
the output of the last time steps.
Best,
Fred
