Because I'm planning to use the kOmegaSSTDES, SpalartAlamarasDES and WHALE turbulence model for a unsteady simulation, I'm expecting using the results of a RANS turbulence model as a IC. I'm wondering, is it preferable to use the corresponding RANS model for the IC, or it doesnt matter at all? For instance, in the case of kOmegaSSTDES unsteady turbulence model, Should I use the result of the RANS-kOmegaSST turbulence model as a IC? Same thing with the SplartAlamarasDES, should I use the RANS-SpalartAlamaras results as a IC? If don't, I'm expecting to use the same RANS results as a IC for all the unsteady simulation. What is your suggestions/thoughts about this topic?
