a problem about user define scalars(uds)

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


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.
