Hi everyone

I have some confuse questions to ask you about the dS[eqn] in DEFINE_SOURCE.

If I set source is equal 0.0 and dS[eqn] is equal an equation. Can I do like that? And what does it mean in FLUENT. (In my intention, I would like to move the sorce terms to the left hand side of equation becuse of the stability of the solution) best regard

dS[eqn] is a linerisation term used to complete the Taylor expansion as shown in the FLUENT manual. It also gives stability to the solution and should be used if possible.

Have a look at "Numerical Heat Transfer and Fluid Flow" by Patankar for information on linearising source terms.

hope this helps
