OMEGA_IMPLICIT in estuaries

[stlaur]

If you run ROMS domains that have realistic bathymetry, resolution <=500m, tides, and your timestep is dictated by Cw, you might want to give OMEGA_IMPLICIT a try (Shchepetkin 2015 https://doi.org/10.1016/j.ocemod.2015.03.006). It's available inside the feature/kernel branch. In our case, the benefits outweighted the trouble of switching to feature/kernel. Pierre

Hi Pierre, I am glad to hear that. I must return to that branch and check what I need to do to merge it into the develop branch. In the ROMS GitHub version, we can switch branches in the build script very quickly by the command:

Code: Select all

build_roms.sh -j 10 -b feature/kernel

It creates the src subdirectory in your project directory containing the code for the specific branch. We always recommend that users update the cloned copy of the ROMS code.
