Hi Al,
I have used for the tracer advection before TS_C4VADVECTION, and to avoid the negative values the TS_MPDATA.
Regards,
Jordi

I have changed the advection scheme and no more negative concentrations in the biology after 10 days of simulation, so the problem is solved. Many thanks Kate for your help.

Many thanks Kate for your answer, I cannot be able to figure out what is the process that makes the biological tracer go to negative values. The negative values appear in the points near the bottom where the fluxes (in Gibraltar strait) are really high (1 sverdrup inflow to Med and 0.9 sverdrup ...

Hi everybody, I am running a Roms setup for the Alboran Sea with bio Fennel model with the last updated source code (version 3.4, updated two weeks ago). My application using only the physics works fine and gives reasonable results. The problem comes when I turn on the bio_Fennel model. It starts ...
