Nodes where both solid and fluid apply deflection

Using preCICE

I had a question regarding how preCICE works when both openfoam and calulix apply deformation at a node.

The fluid reads displacement and writes force and the solid reads force and writes displacement.

If I have a part in the geometry where the OpenFOAM’s motion solver also gives some deflection as well as the solid’ motion. What exactly happens here?

Hi @SomethingRandom,

this question sounds very similar to Couple presiced solidbodyMotion with mechanical deformation.

I think that the problem would be ill-defined if both the solid and the fluid solvers try to move the nodes.
