Dear community,

I am studying the problem of a cylinder oscillating, in vertical direction, in a steady flow. The cylinder has a diameter of 0.1 m, oscillates with a KC of 8 with a period of 300 s, in water. The model is attached here. I cannot attach the mesh because it exceed the maximum file size. If someone is interested, ask me that by mail.

To obtain the cylinder movement I am using the library from the OpenFOAM tutorial "movingCone", including the mesh topology change.

I am looking for the calculation of the forces, particularly the vertical ones.

I have some questions to discuss:

- for this case, what is the best combination for solution schemes;
- how the software calculates the viscous force (considering that the turbolence model has not been implemented);
- if the topology change method is adeguate for this analysis;
- the best boundary condition and the domain dimension.

Waiting for your suggestion.
Regards,
Enrico
