Overset mesh FSI OpenFOAM

Currently, I am working on an overset mesh as part of a fluid-structure interaction (FSI) simulation using preCICE to couple OpenFOAM and Calculix. The boundaries of my overset mesh are successfully deforming in sync with the moving flap. However, I am encountering issues with the movement of the interior cells in the overset mesh; they are not behaving as expected.
I am uncertain if this issue stems from the boundary conditions or potentially an error in how I have defined my dynamicMeshDict file. I have included a link to a video that demonstrates the issue I am facing: https://www.youtube.com/watch?v=vroELwhxOic. As you can see, the first cell inside the overset mesh is not behaving as it should, and I am seeking advice on how to resolve this problem. My dynamicMeshDict looks like this: Code:
FoamFile { version 2.0; format ascii; class dictionary; object dynamicMeshDict; } //dynamicFvMesh staticFvMesh; dynamicFvMesh dynamicOversetFvMesh; //solver multiSolidBodyMotionSolver; motionSolverLibs ("libfvMotionSolvers.so"); solver displacementLaplacian; displacementLaplacianCoeffs { diffusivity inverseDistance (overset1); diffusivity inverseDistance (overset); } Code:
FoamFile { version 2.0; format ascii; class pointVectorField; object pointDisplacement; } dimensions [0 1 0 0 0 0 0]; internalField uniform (0 0 0); boundaryField { overset { patchType overset; type fixedValue; } overset1 { type fixedValue; value $internalField; } walls { type uniformFixedValue; uniformValue (0 0 0); } inlet { type uniformFixedValue; uniformValue (0 0 0); } outlet { type uniformFixedValue; uniformValue (0 0 0); } lowerWall { type uniformFixedValue; uniformValue (0 0 0); } flap { type fixedValue; value $internalField; } } |

Hi, Lundby
Have you solved this problem? I encountered the same problem when using overset grids. |
