New in FLUENT for CATIA V5 4.0

FLUENT for CATIA V5 software is a rapid flow modeling tool that is fully embedded into CATIA V5 and allows design and process engineers to quickly and accurately validate their designs much earlier in the product development cycle. FLUENT for CATIA V5 makes use of a high level of automation, allowing tasks that conventionally require a lot of manual intervention, such as meshing, solution steering, and reporting, to be performed automatically.

FLUENT for CATIA V5 4.0 delivers the ANSYS vision of Simulation Driven Product Development to engineers working within Dassault Systèmes’ CATIA V5 software environment. In addition to performance improvements, this release adds important new physics models to its computational fluid dynamics (CFD) analysis capabilities that extend the types of products for which performance optimization is possible.

Species transport and cavitation modeling capabilities are key new features of FLUENT for CATIA V5 4.0 which has significantly broaden the range of applications available to users. The new species transport model allows the modeling of mixtures of fluids with different properties. This expands the types of equipment for which performance prediction and optimization is now possible to include paint mixers, fire risk detection, airplane cabin ventilation, water treatment systems and the dispersion of exhaust gases. The new cavitation modeling feature lets you predict when cavitation may occur in a variety of systems, including performance optimization of fuel injectors used in car and motorcycle engines. It also lets you see when cavitation may occur in rotating pumps, and make design modifications to reduce the blade corrosion that may result. New heat transfer boundary conditions let automotive companies model the cooling of brake rotor disks, to ensure that optimum braking performance is maintained under all conditions.

FLUENT for CATIA V5 4.0 also brings many new important performance and usability improvements. The new ability to add multiple symmetry planes without the need to modify the original geometry saves you time, both while creating the model, and when performing the calculations. Speed improvements in flow volume splitting save you time when modeling automotive radiators. The new algorithm to build prismatic boundary layer meshes next to solids increases the simulation’s accuracy of, for example, the air flow around car wheels. Other general improvements include an optimized memory management system to handle large models efficiently, and new options that let you easily control the initial conditions for unsteady calculations. These enhancements reduce the time to solution, and make the ANSYS Simulation Driven Product Development vision a reality through ease of use and simulation process robustness. Explore the new features and enhancements FLUENT for CATIA V5:

Geometry and Meshing

  • Ability to handle multiple symmetry planes to reduce model size and computation time. The initial geometry is not modified.
  • Merge fluid option for surface models which allow you to control whether or not the result of flow volume extraction should be a single fluid region or multiple ones
  • "Follow solid profile" for  face selection to make sure that the cap surface at inlet/outlet follows best the initial geometry shape
  • Large speed and memory improvement in the split operation to ease the management of large models
  • Prism layer meshing algorithm improvement in automation and robustness, which is greatly beneficial for complex geometries, especially when sharp corners reside within the geometry
  • Management of group type in correlation with prism layer: When changing group type, you can decide whether to adjust the mesh based on those changes
  • Multiple mesh parts definition improvement for sweept 3D, which makes it easier to  deal with the mesh  of  models like large car radiators,  as well as many sweept 3D mesh parts

Properties

  • “Multiple properties selection” allows you to set the same parameters for multiple properties at the same time, which dramatically speeds up case set-up when there are many fluid and solid zones in the model
  • Creation of mixture fluid data base to support species transport and cavitation new modeling capabilities

Boundary conditions

  • When turning on the “expose coupled wall” option on, you no longer need to update the solution
  • Coupled/uncoupled wall option at the fluid/solid frontiers allows you to control thermal management at these frontiers
  • Consistent way to input parameters for lump models for porous jump and  porous zones, and similarly for  intake/vent and porous/fans
  • Graphical symbols for radiator, porous, porous jump and fan appear on the geometry for easier set-up and acts as a visual check
  • Convection in solid with no holes takes into account the heat conveyed by solids in movement

Physics and Solver

  • Ability to model the transport and mixing of multiple species, which greatly extends the modeling capabilities. This provides a concentration of various gaseous or liquid constituents within the fluid domains.
  • Ability to model cavitation and predict vapor pocket creation in liquid flows
  • “Patch option” provides more control to set initial steady or unsteady calculation conditions
  • Possibility to stop the calculation without saving data which does not overwrite the previous data set
  • Option to set solver iteration number like in FLUENT to control solution process
  • Improved management of the “continue computation “ option when the journal customization is active
  • Easier control of solver and mesh parameter set-up: user can set independently mesh and solver related parameters  using two different slide bars

Post-Processing

  • Additional post-processing capabilities linked to species transport including mass fraction, mole fraction, molar concentration and monitors
  • Additional post-processing capabilities linked to cavitation including volume fraction, monitors and velocity and density for each phase

Miscellaneous

  • Version Information which provides the FLUENT for CATIA V5 version in which original model data was created
  • Improvement in multiple CATIA session handling in order to avoid files being overwritten, and is generated by each session
  • Japanese version available
  •
