Elliptic differential equation
 

Hi,

Has anyone ever programmed an Elliptic Differential Equation (or poisson-like equation) in a UDF in Fluent, whithout the use of the Macro DEFINE_SOURCE? The latter is because I've already programmed 2 transport Equations in a UDF, where the convective flux has to be calculated, and in the poisson equation the convective flux may not be computed.

many thanks for helping me out
