Hello,

I want to simulate the lateral reciprocating movement of a vertical rod inside the water tank (kind of vibrating rod with specified frequency).
Which mesh moving method is suitable in such a problem? I tried the 6DOF solver puting line constraint in the direction of movement. But, it didn't work and goes out of Control (also undergoes rotation).

Do I need to use other method or the above with more precaution.
I can provide the dynamicMeshDict if needed.

Many thanks.

Sincerely,
Sachin

Anybody got any suggestion/s?

Hy! can you solution your problem?I-m in the same situation.

Thanks

Have you tried dynamicInkJetFvMesh? Though there are many ways to do this, dynamicInkJetFvMesh is simple enough for this reciprocating motion. However, the motion is restricted to the x-direction alone. You can transform/rotate your mesh with

transformPoints

and

rotateMesh

to have the piston moving in the x-direction.

entries in the dynamicMeshDict:

dynamicFvMesh      dynamicInkJetFvMesh;

motionSolverLibs ("libfvMotionSolvers.so");

dynamicInkJetFvMeshCoeffs
{
	amplitude 0.1; 
	frequency 100; 
	refPlaneX 0;
}
