Default 6 Degree of Freedom Navier Stoke Equations

Hi. Can I seek some advice about a CFD problem??? I might be doing a project, which involves 6 Degree of Freedom Navier Stoke Equations. This means that the CFD problem has the fluid flow and solid body motion solved simultaneously. The fluid flow influence the motion of the solid body, while the solid body motion influence the fluid flow. Can this be solved using FLUENT software? Currently, I know that in FLUENT solver, the motion of the solid body is fixed arbitrarily and then we find the fluid flow field. But in actual situation, the fluid flow field will influence the solid body motion and in turn influences the fluid flow. Besides using Fortran programming, what other software can I use to do that problem??? Is there a new version of FLUENT software coming up whereby I can do this fluid structure interaction (the fluid affect solid body motion, solid body motion affect fluid. But are solved simultaneously).

Theere is one way to do that work. You can use multi-phase fluid method, and take the solid is very viscos fluid, 1:10000, then you will see the both effects, i.e., solid affect fluid, and vice versa.

Take a look to the CD adapco website. There are people doing this kind of stuff for years now (i.e. floating bodies, etc...): www.cd-adapco.com or www.adapco-online.com

Solid material properties like Young modulus and Poisson dilatation coefficient can be obtain supposing solid is a very viscous fluid ? Is it possible ? Can you explain, please ?

Thx

I don't know about that detail, but what I suggested was one of numerical tricks for dealing moving objects which influences the flow and are influenced by the flow.

FlowVision + ABAQUS can solve this problem, there is an interface between
