Re: Virtual dye sources problem

You want the LwSrc option. This introduces tracer mass without momentum by augmenting the tracer flux divergence at the cell center. It does not impact u,v. For both LuvSrc and LwSrc sources the rate at which tracer is added (in kg/s) is the volume flux (river_transport, m^3/s) multiplied by the co...

Hi all, I would like to add a continuous virtual dye source in my case like river files with NO horizontal momentum transport. Therefore, I utilized a river file to introduce a dye source at a specified location in my setup, while kept river mass transport = 0, and other settings are as follows: ! L...
