Hello,
I want to write a UDF, mass source term. There a thin cylinder in the domain that generates mass flow rate. The source term equation is only a function of time and of course, it will be divided on the total volume of this cylinder zone to get Kg/s.m3 which is the unit for a source term.

The mass source = A* exp((Time - B) /C) / Volume_Zone
where A, B, and C are constants.

Also is the zone volume definition will be different in 2D and 3D?

I will highly appreciate your help. Thank you.
