Dear OpenFoamers,

I would like simulate translating submerged bodies (e.g. sphere) in OpenFoam, with the idea of making the setup robust for most motion described, e.g. for a docking manoeuvre with large translations to investigate hydrodynamic interactions.

I have been able model this in ANSYS-CFX using a moving and re-meshing approach, the purpose of doing it in OpenFoam is to compare & reduce the computational time needed for such simulations. An example of the CFX run is given in the link below:

The closest attempt I've found is the adaptive tet remeshing technique by Sandeep Menon and David Schmidt from their powerpoint below.

I would very grateful of any help given and will be more than happy to post results/documentation of the work in parallel with its progress if allowed.

This stuff is already in OF-1.6-ext. Look for the circCylinder3d tutorial in the moveDynamicMesh section.

The version in 1.6-ext is not parallel, but I have a local version that is.

Dear Sandeep,

That's relief to know. Will do as advised and get back to you on the running it in parallel after.


Thank you for the information =)!

Warmest regards,
Darren
