turbChannel_wallModel crashing near the end of its execution

[luizaldeia]

Describe the bug
The turbChannel_wallModel is crashing after running for around 190/200 time units. The code is reaching an unreasonable CFL, which causes the simulation to fail.

To Reproduce
Steps to reproduce the behavior:
1 - Go to the turbChannel_wallModel example folder: /nekRS-ML/examples/turbChannel_wallModel
2 - Get the running script: ./gen_run_script <system_name> </path/to/nekRS>
3 - Run the case: ./run.sh
4 - The error will occur once the simulation approaches its end

Expected behavior
The expected behavior for the simulation is to run until completion, which occurs at 200 time units. Unfortunately, as we approach the 190th time unit, the timestep starts to decrease, and the simulation fails, potentially due to an unreasonable CFL condition.

Desktop (please complete the following information):
-NekRS v24.0.4

Thank you for reporting the issue @luizaldeia, I'll look into it and see what could be causing the divergence.
