Fluent for turbulence modeling
Hi,
I would like to use a commercial software package for modeling turbulence. The flow under consideration is unsteady, incompressible, with Re ~ 1.0e05. The geometry involved is complicated for which I have an ANSYS model (which I believe can be imported in any solver easily). Most importantly, I need to model (and simluate) the interaction of the flow with a structure which forms an obstruction to the flow. Given loadings (in terms of pressure) from a CFD solver, ANSYS can easily compute the dynamic response of the structure (in bending, torsion, etc) however I would like these displacements to be feeded back to the solver for the next iteration. In this way, I would like to construct an unsteady evolution series of the flow field and the response of the structure to the flow. (Sometimes called flow-structure interaction, or flow induced vibrations). Does anyone have any experience doing this before? Is there any reason to choose Fluent over CFX or CFDRC? I already have ANSYS but the CFD solver for it (FLOTRAN) is buggy, not easy to work with and at times fails to post-process. A finite volume grid size of 200*200*50 would suffice; I have a single P4, 1GB RAM machine to work with and would need results in reasonable amounts of time. Please let me know what you think, many thanks! |
Re: Fluent for turbulence modeling
Ansys now owns CFX. You have to believe that there will eventually be some synergy between Ansys & CFX.

Re: Fluent for turbulence modeling
For turbulence modelling, Fluent offers the most turbulence models, including 0-equation and low-Re models. You can read Ansys data into Fluent easily, but it is hard to read Fluent data into Ansys if your OS is Windows. (easier on Unix) regards emre
