Hello,

I want to simulate several cases of an airplane with flaps and slats at different positions. I would like to mesh the main wing with the Farfield and use this as my "mastercase" when using mergeMeshes. As slaveCases I want to use the flaps, which I also mesh with snappyHexMesh.

Hopefully this way I don't have to re-mesh the mainwing and farfield everytime I change the angle or position of a flap. Well at least this is my idea, but so far I don't know how to properly join those two meshes together.


When meshing the flaps in snappyHexMesh and choosing the locationInMesh at a point inside the flaps, I get only a the mesh of the flap. Using mergeMeshes I can get it to the main wing. But this way the simulation won't work.

I'm relatively new to OpenFoam so I don't know if there is a way to change position/angle of a part (in this case the flap of the wing) without re-meshing everything, except the area around the flap.


If anyone has an idea how I could do this, I would appreciate the help.


Thanks in advance,
Lukas

Hi Lukas,

One way to do this is to use overset. Look for the tutorials in the ESI version of OpenFOAM which would be OpenFOAM-v1812

Hope this helps.
