Point source to a vertical level

How can I add the point source to a specific vertical level?
Eg. If N = 20, then how can we give the discharge at (I, J) positions for N = 10?

Hello,
At present, it is not possible to specify a vertical level for a source via the input files.

You can, however, customize the vertical profile by modifying the ana_psource subroutine in OCEAN/analytical.F, but this requires some code writing.
By default, the vertical profile used is an exponential one.
