Simulation of hydrothermal vent plumes, vertical PSOURCE

edit

Hi All,

I am interested in using CROCO to simulate vertical point sources, at seabed boundary. During our CROCO training this October, we discussed that there is a CPPDEFS Key for vertical PSOURCE but I can't find or remember the name of the key...

Can you please remind me of the KEY name?

I want to capture the vertical evolution and mixing of the plume with a high resolution grid, with NBQ hydrodynamics, nested into a larger grid.

Then I want to capture the horizontal advection, diffusion of the plume in the larger coarse grid. Does the 2-Way AGRIF work in CROCO 1.2.1 in nested NBQ mode? If yes, do both grids need to be in NBQ, or the larger grid can be non-NBQ?

Thank you for any advice! Konstantinos
