Default Unsteady modelling technique?
Posts: n/a

This is my third successive post on unsteady modelling. Basically, I know how to use RANS after 3 years of trying but now I want to look at the feasibility of unsteady modelling.

What are the key things to look at in such simulations? Obviously for steady modelling, emphasis is on correct boundary condition placement/type and grid independence studies. What are the key issues in unsteady modelling? Any help would be much appreciated
