For LuvSrc the volume flux through the cell faces modifies FX and FE in pre_step3d.F. The tracer enters when, subsequently, in step3d_t.F we take the divergence of those fluxes. For LwSrc the divergence of tracer simply appears directly in step3d_t.F. Look in step3d_t.F for "LwSrc" to see where ...

Screenshot 2025-06-04 at 07.22.37.png I ran into same issue with low temperature when I define LwSrc, and the model crashed. The temperature field is wrong because I run this model for summer in the tropical area. I have checked my boundary/climatology/atmospheric inputs, and they are fine. I set ...

Hi,

I downloaded the latest ROMS matlab package and tried to create a contact points file for composite grids.

1. First, I used the dogbone grids:
c_contact('contact.nc', 0, 2);
Gnames = {'dogbone_grd_left.nc','dogbone_grd_right.nc'};
G = grids_structure(Gnames);
S = grid_perimeter(G);
S = grid ...

Hello, all guys, I checked my forcing files, I found the high values in Uwind and Vwind. So I guess the time I started simulation was during a typhoon, and my simulation domain is quete small which may leads the blowup. Now I would change the start time and try it again, I'm not sure if this help ...

Hello everyone. I want to give river in my domain using LuvSrc = T option and the LtracerSrc = T for both salinity and temperature. For checking, I have used the Matlab function map_rivers.m. The direction of the rivers is attached here. I m literally confused about the direction and the position ...

Hi John,

I set N = 1 and river_Vshape = 1, and it turned out the 2D model can work with rivers. Thank you!

Hi everyone,

I am trying to add river sources to a 2D model. The matlab script create_roms_rivers.m works for 3D, and I am not sure if I could just eliminate all the terms related to N/theta_s/theta_b. Does anyone have a matlab file that can create river forcing for a 2D model?

Some concerns:
