Title: a problem about user define scalars(uds)
Post by: chenxizh on June 06, 2012, 10:46:18 AM

Hi, all. Recently I want to use Fluent's user define scalars(uds) in a multiphase problem . I find that the uds in multiphase has the following formulation
(http://hpce.iitm.ac.in/website/Manuals/Fluent_6.3/Fluent.Inc/fluent6.3/help/html/ug/img2694.gif)

So I have a problem about the diffusion term. When I input the value "uds diffsivity" In "Create /Edit Material "  should I multiply by the density and the voidage myself ? Or Fluent will auto multiply the voidage of the phase?
Can anybody help me? thanks.
