I want to describe the filter efficiency with the help of a UDF. So the different zones together represent the filter.nLet´s say the first zone has an efficiency of 50% and 100g/h oil gets into the whole filter, the source term for the first zone corresponds 50 g/h (units for source terms disregarded).nNow the second source term needs the information of the first source term how much oil is captured in the first zone, and so on and on. But this efficiency changes with time because of different saturations, velocities etc. So the information of the first source term isn´t constant.
