Continuing the discussion from [Request for pointVectorField pointDisplacement from objectRegistry region0 failed | available objects of type pointVectorField are 0()](https://precice.discourse.group/t/request-for-pointvectorfield-pointdisplacement-from-objectregistry-region0-failed-available-objects-of-type-pointvectorfield-are-0/658/8): I want to continue the post because I have the same problem when using new Mesh Motion Solver in _dynamicMeshDict_. What motion solvers does preCICE OpenFOAM adapter support besides **displacementLaplacian**? How can I extend the adapter if I want to use a new mesh motion solver? The motion solver works without preCICE but fails after turning on the coupling. > **dynamicMeshDict** > > ```c++ > > dynamicFvMesh dynamicMotionSolverFvMesh; > > motionSolverLibs ("libRBFMeshMotionSolver.so"); > motionSolver RBFMeshMotionSolver; > // Settings for the RBF solver > staticPatches ( upperWall lowerWall front back); > movingPatches ( flapBaffle_master flapBaffle_slave ); > fixedPatches (inlet inletWater outlet); > interpolation > { > function TPS; > } > coarsening > { > enabled no; > } > > ``` > [@Request for pointVectorField pointDisplacement from objectRegistry region0 failed | available objects of type pointVectorField are 0()](https://precice.discourse.group/t/request-for-pointvectorfield-pointdisplacement-from-objectregistry-region0-failed-available-objects-of-type-pointvectorfield-are-0/658/8): > > I understand now that the problem is really that the mesh motion solver (you are using [multiSolidBodyMotionSolver](https://www.openfoam.com/documentation/guides/latest/api/classFoam_1_1multiSolidBodyMotionSolver.html) does not define `pointDisplacement` in the same way as e.g. `displacementLaplacian` .

If yes, then you would also need to modify our `Displacement.C` accordingly. @Makis, Can you explain this further? I’m afraid I will mess up `Displacment.C` and `displacementLaplacian` will not work. ---

I found one issue that the mesh motion solver does not use the `pointDisplacement` file to move the mesh, whereas preCICE needs this file. ---
