ANSYS Releases FLUENT for Dassault Systemes’ CATIA V5 5.0

By DE Editors

ANSYS’ FLUENT for CATIA V5 software integrates computational fluid dynamics into PLM. It’s technology is based on Dassault Systemes’ open SIMULIA scientific platform and the underlying CAA V5 architecture.

ANSYS has created a PLM-integrated CFD solution that reveals the effects of fluid dynamics during product design. According to the company, it generates files that are 100 percent compatible with ANSYS’ CFD software, FLUENT, allowing users to move back and forth between FLUENT for CATIA V5 software.

The volume of fluid (VOF) model has been introduced in FLUENT for CATIA V5 5.0. The VOF model is useful for modeling two-phase flows with a long free surface. This model is useful for applications where two different fluids, typically a gas and a liquid, are interacting with each other. These include fuel cells, ship and boat hydrodynamics, water pumps, and fuel tanks.

Other enhancements include more robust flow volume creation, user defined coloring of inlets and outlets, total heat flux specification for walls, periodic specification icon for periodic boundary conditions, and appropriate error messages when meshing volumes using the Tgrid filler.  Several enhancements have been made for large model handling, such as consistent numbering and highlighting of solid and fluid sides of walls. For problems involving mapping of pressure or temperature data to FEA models for Fluid Structure Interaction, it is now possible to select geometric features from the viewer or solid features from the specification tree as supports.

Several changes have been made to the post-processing capabilities. The icon groups have been reorganized and new capabilities have been added. A new icon group has been added for vector plots and the post-processing icons for contour, vector, and pathline plots have been grouped together to make them more compact and accessible. It is now possible to create cut planes easily to create slices through 3-D geometry for plotting. Turbulence at walls can be plotted using the additional y+ quantity. 

For HTML reporting, plots made on the full geometry created using Image Transformation will be included, and the total power due to torque will be reported for rotating walls. Plotting and reporting capabilities have been added for the VOF model. It is now possible to use CFD-Post as the external post-processor, allowing the creation of plots and reports for both steady state and transient data.

Solution initialization will now allow users to initialize from a boundary and to specify a liquid height for open channel flows. It is now possible to run a calculation without any convergence criteria. Finally, FLUENT for CATIA V5 5.0 has upgraded to the latest version of the FLUENT solver, ANSYS FLUENT 12.0.
