Good day everyone,
I am trying to run a simulation using solids4Foam, the final objective is to simulate a pipe that is rotating (around Z axis) and vibrating (oscillating in the Y axis direction) in the same time.

The blockMesh is composed of the patches inlet, outlet, inner-wall, and outer-wall

First I got the simulation to have a simple rotation without vibration by using the boundary condition of:

- inlet & outlet: zeroGradient
- inner-wall & outer-wall: fixedRotation

Second I got the case to vibrate without a rotation by using the boundary condition of:

- inlet: solidTraction
- outlet: fixedDisplacement
- inner-wall & outer-wall: zeroGradient

Both cases have the following:
- mechanical Model as neoHookeanElastic
- fvSchemes set as Euler in both d2dt2Schemes & ddtSchemes
- solidModel as nonLinearGeometryTotalLagrangianTotalDisplacement

when I tried to combine the two movement... rotational and oscillation, the model only rotate and does not oscillating an the is no effect for the solidTraction on the inlet what so ever.
using the following boundary condition of:
- inlet: solidTraction
- outlet: fixedDisplacement
- inner wall Outer wall: fixedRotation

So I tried to change the boundary to the following:
- inlet: solidTraction
- outlet: fixedRotation
- inner wall Outer wall: zeroGradient
However the problem here was that the outlet is rotating, causing deformation for the pipe and the rotation do not move along the pipe mesh, and still there is no effect of the solidTraction

Does anyone have idea is it possible to achieve two movement in the solid mesh simultaneously (Rotational movement & linear deformation along an axis) ?
