Fluent Inc., in its continued commitment to providing CFD simulation technology to the process industry, releases MixSim 2.0 for use in modeling industrial mixing tank applications. MixSim has a mixing specific interface and is fully coupled with Fluent Inc.'s other packages (GAMBIT 2 for geometry and grid generation, and the FLUENT 6 solver for solver and physical models). The new intelligent geometry and meshing algorithms in MixSim 2.0, combined with mixing specific graphical presentation of results, enables users to set up CFD simulations of complex mixing tank configurations in a matter of minutes.

Uniquely in MixSim 2.0, the code allows for multiple arbitrarily positioned shafts and baffles with various top and bottom vessel shapes. MixSim's coupling to libraries of brand name and generic impeller types also leads to rapid mixing tank problem set up and solution for parametric mixing related analyses. Connection to the unparalleled breadth of physical and chemical models in the FLUENT 6 CFD solver means that users now have the most powerful flow modeling software available to them for mixing tank calculations.

Dr. Jochen Schütze, MixSim Product Manager, announcing the release of this second-generation product comments: "We believe that MixSim 2.0 is a significant milestone in CFD modeling technology for the mixing community. MixSim's level of customization and flexibility and its ability to model complex mixing tank configurations, will make CFD more broadly accessible to mixing practitioners." Mixing expert and consultant, and long time CFD user Ron Weetman, adds to these observations: "I have been a user of earlier versions of MixSim for several years now and I believe MixSim 2.0 brings additional and much needed modeling power and flexibility to the mixing community."
