Hello,

I am currently doing a simulation (airfoil) to compare between openfoam and fluent.

The mesh was done in ICEM and converted to openfoam format using fluentmeshtofoam. However, when the mesh was converted it was expanded in the z-direction by 0.57m (It extruded from -0.28 to 0.28 in z-direction) and it kept the length as 1m.

After setting up the simulation and running it, I can't get results that are similar to Fluent results (e.g. In fluent Cl =0.507, Cd=0.027 and in OF Cl= 0.326 Cd=0.0123). I tried to use different reference areas (1m2, 0.57m2, 1.57m2). But the area that gave me the best results was 0.28m2. Is there a way to find out what is the correct reference values to use when setting up the case ? I tried to use paraview to get the surface area of the top part of the airfoil and it was 0.57m.

I am trying to run the simulation inviscid and the case and mesh files are in the link below.

Any help would be appreciated.

Thank you
