[MITgcm-support] segmentation fault

[Samar Khatiwala]

Hi Riema

Sorry I haven't been able to respond. I've been buried in work and  
its been hard to find time to think about your
problem.

As I said, there is no magic formula for this. The time scale is  
there to filter out the diagnosed phase speeds
that can be quite noisy. One thing you can do is monitor the  
diagnosed phase speed at a few grid points as a
function of time and use that to tune the cvelTimeScale.

I also don't have much advice on a purely barotropic simulation. I  
have never forced the model through a
prescribed eta like you do. So I can't say why you get a phase error  
in the velocity. What I find strange
about your setup is that you prescribe eta at both ends but then  
apply a radiation BC on Uvel. It doesn't
sound right at all. I think you want to prescribe eta and U at one  
end and let the radiation BC do its thing
at the other end.
