I'm intending run a direct FSI simulation and I didn't find help and I did both Ansys multiphysics and the CFX models and I running the Ansys Launcher with MFX but don't happen nothing. I checked the folder (working directory) and there is only a ".err" file that says "Fatal error notification received The reported error is Process CFX encountered the error: -11000." I don't know where can I find help or documentation for doing this kind of simulations, if anybody can help me I'll be grateful, Zerocles

I know there isnt a two-way FSI tutorial in the CFX manual but isnt there one in the multiphysics manual? I'm sure there was?

Use that to get a known-good model working before you model your own system.
