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:

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.

Thank you for your help, but I already know how to set up laminar and turbulent cases. I just don't know how to do it without considering viscosity. I need inviscid cases. I am preparing a tutorial for my university and it need to be inviscid.

Thank you

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 ?

[Artur]

Apparently some people have already tried that:

Perhaps if you dig deeper you will find the answers you are looking for.
