Fluent Inc. releases version 5.5 of its FLUENT software

Fluent : 21 December, 2000  (New Product)
GT-Power is one-dimensional gas dynamics and engine simulation software developed by Gamma Technologies, Inc. (Westmont, IL). It is commonly used in the automotive industry for engine simulation. FLUENT 5.5 offers an option for users to couple their FLUENT simulations with their GT-Power simulations. This makes it easy for engineers to integrate their CFD flow modeling of components with the big picture, system-level simulation in GT-Power. Technological wizardry built into this coupling also makes the process fast and computationally economical. Currently, the coupling can take place in several areas of the simulation: velocity inlet, mass flow inlet, pressure inlet, and pressure outlet. To take advantage of the GT-Power/FLUENT coupling, users need a specialized license and the GT-Power library, specifically built for this coupling, from Gamma Technologies. Initially, this capability will be available on selected platforms only, with additional platforms planned for the near future.
Fluent Inc., worldwide leader in computational fluid dynamics software, announces the release of FLUENT 5.5. This newest version offers advances in almost every category of functionality, accuracy, speed, flexibility, and ease-of-use, with special engine modeling capabilities geared toward the automotive industry.

FLUENT and GT-Power Team Up
GT-Power is one-dimensional gas dynamics and engine simulation software developed by Gamma Technologies, Inc. (Westmont, IL). It is commonly used in the automotive industry for engine simulation. FLUENT 5.5 offers an option for users to couple their FLUENT simulations with their GT-Power simulations. This makes it easy for engineers to integrate their CFD flow modeling of components with the big picture, system-level simulation in GT-Power. Technological wizardry built into this coupling also makes the process fast and computationally economical. Currently, the coupling can take place in several areas of the simulation: velocity inlet, mass flow inlet, pressure inlet, and pressure outlet. To take advantage of the GT-Power/FLUENT coupling, users need a specialized license and the GT-Power library, specifically built for this coupling, from Gamma Technologies. Initially, this capability will be available on selected platforms only, with additional platforms planned for the near future.

The technical framework used for the GT-Power coupling gives FLUENT an easy platform on which to build future couplings with other one-dimensional analysis packages.

Improved Accuracy, Speed, and Flexibility
According to FLUENT Product Market Manager, Nicole Diana, FLUENT 5.5 offers across-the-board improvements. 'We now have a new optional algorithm for particle-path integration, which improves the accuracy of particle tracking. In addition, you can now model up to 50 species transport equations, which is critical for our users who are modeling finite-rate chemistry involving detailed reaction mechanisms. We've also added parallelization to the popular thin-plate conduction model, to speed up the process and help our users with large and complicated geometries,' she says.

For monitoring and postprocessing FLUENT results, a key new feature is access to residuals for all solution variables, which is useful not only for diagnosing solution convergence, but also for troubleshooting non-convergence and divergence.

It's now possible to import meshes in CFD General Notation System format into FLUENT and export data and results to CGNS format as well. Two additional new formats are available for exporting data: ANSYS and Abaqus. Also, several improvements have been made to NASTRAN and PATRAN data export.
