Solid body motion on boundary and not entire mesh

twinturbotom · July 15, 2019, 21:59

I hope to use linear motion to move an internal boundary.
I have modified "wingMotion2D_pimpleFoam" to move the "wing".

When starting pimpleFoam I see: Applying solid body motion to entire mesh

The domain and wing move together (as the output says) but I only want to move the wing.

Below is how I modified the dynamicMeshDict file.

Any ideas?

Thanks!

Code:

dynamicFvMesh dynamicMotionSolverFvMesh;

solver solidBody;

solidBodyCoeffs
{
    patches             (wing);
    solidBodyMotionFunction linearMotion;
    linearMotionCoeffs
    {
        velocity        (1.0 0.0 0);
    }
}

Hey Tommy Mello, I have a similar problem. Was wondering if you figured out how to move only the wing.
