Interim Depth variable
 
Hi

I'm trying to make a custom executable to compute the concentration of a scalar. As an input to the source/sink computations I need to know the depth of water. This is available as a post process variable, but does not seem to be readily available during the run.

Do I need to run from the water surface (where source/sink occurs) down through the cells looking for the model invert or is there a variable that would give either the depth or distance to the invert at a cell?

Alternate poor idea. Run model once, output post processed depth at all the cells, then run again using saved results as input to the scalar computation.

The depth is a postprocessed quantity, so you'll need to compute it from the fluid fractions and volume fractions in a particular column of cells.
