Blowing up problem

#1 Unread post by dhd_1979 »

I have a succesful modelling of an area using a grid of 116x156x32, but when I changes the grid size of the same area to 0378x0358x032, It blows up just at the beginging, Could any one help me? the following is the output the model:

Did you change the timestep when you changed the resolution? How about the bathymetry steepness factors - did they change? You can also adjust the horizontal viscosity and diffusion coefficients.

Thanks Kate!
I have change the time step from 720s to 90s, and the Maximum grid stiffness ratios: rx0 = 3.069334E-01 (Beckmann and Haidvogel) rx1 = 9.416266E+00 (Haney).

The SST and speed at the beginging is

.

It seems that the NaN propagates from the east to west, so I have test the east boundary for both close and open conditions, but the result not changed.

I also change the depth of the bathymetry to a constant 800m, the result still not changed much.

You also have trouble moving west to east. The trouble is moving as a barotropic wave, in the depth-integrated equations. At least it is happening early, which makes it easier to investigate. I don't know what it is - perhaps you can let us know when you fix it.

Did you smooth your bathymetry?

Thanks LiuZHQ!

I smoothed the bathymetry with rfac=0.35(maximum slope of topography allowed in smoothing), and I have a test with the bathymetry to be a constant 800m, it is no useful.

I changed the initial state from levitas climate data to hycom exp08, but still no useful.
