Bug with time-dependent bathymetry and PERFECT_RESTART
Strictly speaking it is a bug, but it only affects users with a really specific combination of options. When one sets LcycleRST == F in combination with SED_MORPH and PERFECT_RESTART, ROMS tries to write bath to an index exceeding the dimension bounds ( three ) at the fourth WRT_RST. It is an issue ...

Re: Errors when computing DAMEE 4 testcase
The error is pretty self-explanatory. You've defined more than one horizontal and vertical advection scheme for tracers in your .h file.
Look through your .h file and make sure there is just one TS_*HADVECTION and one TS_*VADVECTION option defined.

Re: Post subject: Error while processing Climatology multi-f
It seems you are using COAWST. Which means you are likely using roms_master_climatology_coawst_mw.m to create clm, bdy, and ini files. In this matlab script the clm file is created first with all its time variables. In updatclim_coawst_mw.m you should see: tempid=netcdf.inqVarID(RN,'ocean_time'); ne...

Re: Post subject: Error while processing Climatology multi-f
This is clearly the problem. Check if the calculation of ocean_time is different from zeta_time/v2d_time/etc, because these other time variables seem to be what you want.ocean_time = 4858099200, 4858185600, 4858272000, 4858358400, 4858444800,

Dear all, I've recently gained access to a Cray XC30 machine and am trying to run COAWST experiments on it. I'm posting my question here instead of on the COAWST forum because I'm only using the ROMS component of COAWST for now. With the Cray fortran compiler and -O3 optimization the model compiles ...

Re: very early blowing_up
Smoothing your bathymetry will probably solve your problem. Your current rx0 and rx1 values are too high: Maximum grid stiffness ratios: rx0 = 8.101426E-01 (Beckmann and Haidvogel) rx1 = 2.460969E+01 (Haney) If you search this forum you'll find that rx0 values are usually recommended to be < 0.2 and...

A linear programming matlab code can be found here.
However, these matlab scripts seem to be 6 years old already. For instance, Vstretching = 4 is not supported.

Could it be that you've forgotten to move the ocean_rst.nc file to your header/project dir (the directory where you have your .h file) ?

Re: Problem of "Undefined function or variable "fcn"." in RN
Check point 9 in the MexCDF FAQ:
http://mexcdf.sourceforge.net/faq.php9. Why do I get Undefined function 'fcn' when trying to use ncmex?
You are trying to use the NetCDF Toolbox, which I do not support. See the previous three items.
