Re: Blowing up of south china sea in COAWST
The first thing I would do is change NINFO from 30 to 1 so that you have a better chance of watching things go bad. The second thing I would do is change Vtransform and Vstretching to 2 and 4, respectively.
You have a negative DZmin, perhaps because of the above problem with your vertical coordinate system since your hmin is under water. Your horizontal grid has a significant range of dx,dy values - making sure the grid varies smoothly is important too. Will you show us the grid?

thanks for reply.
I have modified the NINFO, Vtransform and Vstretching as your advise.
I also modified the depthmin to 15, depthmax to 5000 of the grid file.
Here are the result file and my grid picture.
what's the problem? Thanks a lot.
