Ocean Modeling Discussion

Dear Sara, I'm not sure what you mean exactly by "lower level", but I can recommend a couple of very nice first-entry books in ocean modelling I've red in the past. 1)Ocean Modelling for Beginners, and 2) Advanced Ocean Modelling; they are both written by Jochen Kämpf, Springer ed. Again, these ...

Thanks again for the time and input. I had already set the stack size to unlimited and still didn't work, so this was not causing the problem. PROBLEM SOLVED : It turned out that I had to put all my files in the same directory: i.e. the HPC infrastructure that I'm using has two separate file systems ...

Thank you for your answer Aminrahdarian. My domain is indeed large (1024 x 512 x 30), but as I described in my question I already ran this configuration without any problems on my home cluster which has 8G of memory on each of its' three nodes. On the contrary, the HPC machine I am trying to run the ...

Greetings, I have the following problem: My model setup hangs right after initialization without giving a very usable output in order to debug it. The application is on an HPC infrastructure, and I am using the gnu compiler and a serial setup in order to be able to use the ROMS debugger. The message ...

I managed to solve this by changing slightly the borders of the refined grid, in coarse2fine.
It seems that the complex geometry of the Donor grid interferes with the refined, as I illustrate in the graph.

Moreover, when I run the exact same model set up with a refinement factor of 7 for the fine grid, the model runs.
The problem is that I get this error when I try it with ref. factor 3 or 5.

Thanks for the answer. I'm sorry... I miss-copy-pasted the wrong debug. I edited my post with the correct debug output.

Hi, I was wondering if anybody came across this before. In my nested application, it seems like the code is assigning the coarse grid as 00 instead of 01. Also the timestep ratio is zero instead of 3. Refined Nested Grid(s) Information: ================================== Refined Donor Refined ...

I am guessing that the source of this, is in the way the code 'jumps' from an open coast segment to the next. When a shoreline is interrupted by the Basemap function, the topology changes and so does the distinction between land and water. When I ran into a similar situation, I solved it by ...

I attached the two files that were in the url I sent you. The second one is the application and the first one is probably an example. I have not used these before, so I cannot tell about their working condition. I build my grids with pygridgen-pyroms and never used seagrid. Maybe you can get more ...

Hi, maybe you can download it from here

I guess it's an area related issue because the page is up and working.
I've attached a file with the wiki page, so that you can at least see the instructions.

Cheers,

Hello, as part of my ROMS learning procedure, I set-up a very simple realistic application in the Mediterranean, with atmospheric forcing, rivers, boundaries and a simple square grid with a refined two-way nesting. It ran flawlessly and after some tweaking of parameters (basically hor.diffusion and ...
