Re: PYROMS error

Error #1 is probably because you did not install the lp-solve library or Pyroms does not find the path to it. The paths can change depending on how you installed the packages. I use pyroms inside a JupyterLab (a docker image) and the following commands installed it for me. "jovyan" is the ...

But this is not related to the original problem of this post.
Now, I need to adjust better the grid and bathymetry.

So, the original problem was solved!
Thanks!

I thought dt parameter was an integer. :oops: I tested it with 0.5 and the max barotropic courant was higher than 1 (the model crashed - step 23). But with dt <= 0.3 the Courant numbers are okay, so I adopted 0.25. Now, I will let t...

Barotropic model Blowing-up with high courant and dt = 1.

Hello, This is my first post here. So, I would like to say thank you for accepting me and for all ROMS developers for the tool and support. I am modeling my first problem with ROMS. It is a 2D model (barotropic only) with a resolution of 10m. [Problem] The model is blowing-up in step 9 with high bar...
