FSI analysis-time steps for transient analyses -- CFD Online Discussion Forums

seb Guest Posts: n/a	Hi, I am modeling a wind blade using the FSI solver. The FLOTRAN analysis is transient. The FSI analysis is transient for SOLID and FLUID analysis. I have two questions: - how to define the FLOTRAN time step value in comparison to the FSI time step value ? (Choosing the user-defined time step (or perhaps it is better to use advection for TIME STEP CONTROL)??) - how to define the values á and â for the damping (proportional damping)? Thanks everybody, ciao Seb
