With CFD software ?

Julien Mazallon

I'm at present using on a daily basis Ansys(Emag&structure) and Promechanica. Now I'm planing to aquire a CFD code for our specific requirements:

-liquid mono and multi species.

-laminar and turbulent flow.

-compressible and uncompressible.

-sub and supersonic flow (Mach<3).

-ability to have transient mesh displacement

(typicaly: moving ball in an hydraulic valve)

Is the best option to get Ansys Multiphysics with Flotran, to have the ability to do coupling fluid/structure or must I buy a software only dedicated to CFD (Fluent, StarCD, Flow3D, etc ....)? Is Flotran as efficient as the other codes? What are the differences?

Any opinion will be greatly appreciated!!
