Hello everyone. I am doing my final degree project in OpenFOAM v8.

My project is about studying how a 2D fish (NACA0012) is affected by a perturbed waters at high reynolds (Re=6*10^6). In order to do this I created a mesh following the youtube tutorial of Sebastiano Stipa https://www.youtube.com/watch?v=72RvIkETWLg&t=6s.

Now I have done three meshes: the first one is as the video, very coarse, the second one I doubled the cells and also the zgrading; the third one, has doubled the cells and zgrading of the middle mesh.

Then in order to corroborate if the mesh is alright I contrasted with NASA research about 2D simulation on NACA0012 (https://turbmodels.larc.nasa.gov/naca0012_val_sa.html). After a lot simulations I have finally get to a CD=0.0085 if I put leadgrading=0.000001

Then I changed the U vector to have a velocity field of 10º, but I cannot match the data of NASA. So I will leave my middle mesh folder so anyone can investigate; I have not included the cylinder because that's the next step.

So if you are going to try, just do./Allrun or blockMesh; extrudeMesh and then simpleFoam. (The folder is prepared to run for U=51 m/s alpha=0º) (u must change the U file to match the data here https://www.openfoam.com/documentati...irfoil-2d.html)
