NetCDF: Start+count exceeds dimension bound

#1 Unread post by abhay »

Hi

I have configured my first ROMS application and have the executable in my work directory. When I try to run it, I get the following error:

I did not use the scripts available on the website to generate my grid, populate the initial conditions, forcing fields etc. , however, I referred to the guidelines and instructions provided on ROMS Wiki. The initial conditions are generated using Matlab. Is the order of the dimensions in the initial condition file (xi, eta, s) enforced strictly? I wouldn't think so, but then I am not able to understand why it would fail to read the file.

If a similar issue has been addressed then I'm sorry for re-posting.

Thanks in advance.

yes the dimensions are strictly enforced.
If you are new, i would recommend to use m files from someone/somewhere that already work. It will save you a lot of time.

Hi John

Many thanks for helping me out. I made the changes and it works now :)
