Hello
I am trying to avoid creating a large background mesh for my rigid body to move in. I am simulating a motorcycle moving from rest to 30 m/s over a period of 3 seconds. I have implemented overset meshing with three component meshes merged into a background mesh. The background mesh is currently 50 meters long. I would like to use the drivenLinearMotion motion function implemented in v2106 to move the background mesh with the component meshes. All cellzones have been correctly identified with topoSet and setFields. I have tried implementing it as follows in the dynamicMeshDict: dynamicFvMesh dynamicOversetFvMesh; motionSolverLibs (fvMotionSolvers); solver multiSolidBodyMotionSolver; multiSolidBodyMotionSolverCoeffs { All { motionSolverLibs (libfvMotionSolvers); motionSolver solidBody; solidBodyMotionFunction drivenLinearMotion; cellzone All; cOfGdisplacement CofG; } RR { solidBodyMotionFunction tabulated6DoFMotion; cellZone RR; tabulated6DoFMotionCoeffs { CofG ( 0 -0.00506 0.35172); timeDataFileName "RR_sixDoF.dat"; } cOfGdisplacement CofG; bodyIdCofG 1; } rearWheel { solidBodyMotionFunction tabulated6DoFMotion; cellZone rearWheel; tabulated6DoFMotionCoeffs { CofG ( 0 1.70675 0.3826); timeDataFileName "rearWheel_sixDoF.dat"; } } frontWheel { solidBodyMotionFunction tabulated6DoFMotion; cellZone frontWheel; tabulated6DoFMotionCoeffs { CofG ( 0 -0.00506 0.35172); timeDataFileName "frontWheel_sixDoF.dat"; } } } The result of the simulation is that the background just doesn't move whilst all the other specified motion works as intended. Any help would be greatly appreciated! James |
