Movement of structures with overset mesh

Using preCICE

Hi everyone, I am using overset mesh to simulate a structure moving at a constant velocity. preCICE only supports a few motion solvers of openFoam. I tried to apply velocity in the solid solver Calclix, but then the overset mesh don’t move with the object. For the dynamicsMeshDict file as follows: Do you have a good way to apply velocity in dynamicsMeshDict?

dynamicFvMesh   dynamicOversetFvMesh;

motionSolverLibs (fvMotionSolvers);

solver          displacementLaplacian;

displacementLaplacianCoeffs {
    diffusivity quadratic inverseDistance (floatingObject);
}

Hi @daosheng_ning,

we currently don’t have an example with overset grids, and we are looking for one: Needed: Tutorial with OpenFOAM and overset mesh · Issue #335 · precice/tutorials · GitHub

If you manage to set up something, contributions are very welcome!

I added the overset tag in this topic, you might be able to find some clues via that: Topics tagged overset

I think you should try adding oversetmesh boundary condition to displacementLaplacianCoeffs section.

@Turan do you maybe have an example of how this should look like, or a link to related documentation?
