Hello,
I need to prepare a inviscid simulation over a NACA0012 using OpenFoam, but I can't think how to use openfoam to solve the inviscid flow. I am using a basic mesh created in ICEM and converted to OpenFOAM. Any idea or recommendations ? Thank you |

I have checked that already, but apparently it uses Spalart Allmaras as a solver.
I know how to set a simulation using RANS and other turbulence models, but I can't find out how to set up a inviscid simulation like you would do in Fluent. Any idea ? thank you |

I'm not entirely sure what you mean by:
Also, Spalart-Allmaras is a one-equation turbulence model. For more info see: http://www.cfd-online.com/Wiki/Spalart-Allmaras_model if you want to use a different one (k-epsilon, k-omega, etc.) you should edit the constant/RASProperties file, adjust the boundary conditions in your 0 directory and schemes and solvers in system/fvSolution and system/fvSchemes files. |

I'm sorry, I totally didn't understand your question. There is the potentialFoam solver which should do what you want although I've only used it once.

I still don't get it. Is it possible to modify the solver (simpleFoam) and remove the viscous terms ?

Apparently some people have already tried that:
