Hello Fluent community!

As many others here, I need help, and I'll go right to the point.

I'm spreading some posts across the sub forums, as my doubts are of different categories, but i'll be linking them all here(I'm still editing them, so they might not be ready yet).

Summarising my case:
- I want to simulate a transient dispersion of a denser than air gas using fluent(VOF multiphase case).

Things I need to do but I don't know how to:

1. I've got to define a wind profile at t=0 equal to the result of a previous, steady state, simulation performed on the same mesh.
- Is there a way of defining an initial wind profile like this?
- Are there problems on doing that?

2. UDF "Step" function(only if "1" is not possible): No post Yet

3. Boundary Inflation: No post Yet

Sorry for any bad english, I'm from Brasil. And sorry for bothering you with my own problems.
