Flutter Analysis of a Wing with FSI
 

For my current project, I am trying to do a flutter analysis of a wing. My problem is that, what should be the work flow of a flutter analysis in ansys using fluent and FSI technique ?

Like for example in this paper flow chart as seen suggest this way => first do a fsi analysis and valide the stresses in static stractural analysis and from there use that stresses as prestresses in modal analysis and get the results. But I have seen an ansys webinar that suggests the otherwise, like modal analysis first and transfer that mode shapes to cfd and etc(using cfx). My question is that which way is the right path for me to acquire the flutter speeds and other paramethers. thanks in advance.
