    Hello ppe1906, 

    What I would do is, import the model in hypermesh, create a boundary box accordingly to the conditions, do a 2d surface mesh in hypermesh for all the geometry (model and boundary box), export the mesh as .arm or nastran format, and do a 3D  volume mesh in acusolve, apply different boundary conditions in acuConsolve and solve. 

    I will share if I find any tutorials.

    There are couple of tutorials in the latest version of AcuSolve that have external aerodynamics for Airfoil. 

    ACU-2100: Turbulent Flow Over an Airfoil Using the SST Turbulence Model

    ACU-2200: Transition Flow over an Airfoil Using the SA Transition Models

    Oops they were hard coded with my installation folder. 

     

    If you open AcuConsole and go to AcuSolve help, you'll find these tutorials. Every AcuSolve  installation has these. 

     

    There is a PDF document in the installation folder \doc with all tutorials.
