Flow Science Releases FLOW-3D/MP v4.0 for CFD

Flow Science, Inc. announces that a new release of the distributed-memory version of its FLOW-3D computational fluid dynamics (CFD) software, FLOW-3D/MP, is now available.

FLOW-3D/MP Version 4.0 offers substantial performance improvements, including significant decreases in problem setup and simulation times. Crucial developments to the software have reduced the amount of data sent via MPI communication, cut down on the number of synchronization points and improved computational load balancing using the automatic domain decomposition tool (ADT). ADT allows users to decompose the domain quickly and efficiently, instead of relying on a tedious and often inaccurate manual procedure. All of this makes it possible to extend scaling to up to 32 cores and achieve runtime improvements of as much as 16x.

The physical models and numerical methods of FLOW-3D/MP v4.0 are based on FLOW-3D v9.3.2.

“This new version will enable our user community to achieve highly-accurate and reliable answers in a half day or less which might have previously taken a week,” said David Souders, Flow Science’s Vice President of Sales & Marketing.

FLOW-3D/MP, first released in 2006, uses multi-block methodology to decompose the computational domain into blocks, which are then distributed among the nodes in a cluster. FLOW-3D/MP has been benchmarked and tested extensively on both Windows Compute Cluster and Linux workstations. 

Flow Science has commenced shipment of this new release to customers under maintenance contracts.

Pointwise Releases Gridgen v15.15 for CFD

Pointwise today released the latest update to its Gridgen meshing software for computational fluid dynamics (CFD) with new tools for drastic size reductions in hybrid meshes.

"Customers love hybrid meshes because they can be generated very quickly using Gridgen's T-Rex technique, but the resulting meshes can be very large," said Dr. John Steinbrenner, Pointwise's vice president for research and development. "In the latest Gridgen release, improvements to the algorithm that combines tetrahedra into prisms produce up to a 57 percent reduction in total cell count relative to the previous version of the software."

Gridgen's T-Rex technique extrudes layers of high quality, high aspect ratio tetrahedra for boundary layer resolution, gradually transitioning to isotropic tets away from the body. An optional post-processing step combines adjacent tetrahedra into pyramid and prism elements in the extrusion layer. Prism recombination was frequently halted in previous versions by mesh quality issues and cell topology restrictions on symmetry planes. By removing many of these limitations in the new Gridgen Version 15.15, final cell counts can be reduced dramatically. Customers benefit because a smaller grid requires less memory, runs faster in the CFD solver and produces results sooner.

"A 27 million cell mesh for a modern, complex fighter aircraft was reduced to 12 million cells, and similar reductions were obtained for the AIAA shock boundary layer interaction benchmark case," said Steinbrenner. "Combined with the automation of this technique, these smaller meshes make hybrid meshing very effective for the CFD practitioner."

Pointwise, Inc. is solving the top problem facing engineering analysts today - mesh generation for computational fluid dynamics (CFD). The company's Gridgen and Pointwise software generates structured, unstructured and hybrid meshes; interfaces with CFD solvers, such as ANSYS FLUENT, STAR-CD, ANSYS CFX and OpenFOAM as well as many neutral formats, such as CGNS; runs on Windows (Intel and AMD), Linux (Intel and AMD), Mac and Unix, and has scripting languages that can automate CFD meshing. Large manufacturing firms and research organizations worldwide rely on Pointwise as their complete CFD preprocessing solution.

Exa Releases PowerFLOW 4.2

USA Exa® Corporation, a global innovator of fluids simulation (CAE/CFD) software for product engineering, announces a new release of its flagship product, PowerFLOW®.

PowerFLOW 4.2 simulates true rotating geometry – an industry breakthrough that enables practical and accurate prediction of fan noise, fan performance, brake cooling and wheel aerodynamics. In addition to improved accuracy and simulation process turn-around time, PowerFLOW 4.2 also offers the ability to simulate long-term transient thermal protection situations such as key-off and soak.

PowerFLOW 4.2 simulates true rotating geometry for accurate prediction of fan noise, fan performance, brake cooling and wheel aerodynamics.

Since its inception, Exa Corporation has been committed to the seamless integration of simulation and analysis into the engineering process. This new release continues the mission and offers capabilities that further enhance accuracy and overall turn-around time. “With PowerFLOW 4.2 and true rotating geometry, not only are we handling real-world applications that were not practically possible before, but we are also providing tools, templates and physics improvements that streamline the simulation process, enabling product performance analysis to be performed at the very earliest stages of design,” commented Charles Alexander, Exa’s Director of Product Management for Simulation Products.

True rotating geometry, frequently called ‘sliding mesh’ by the simulation community, simulates the actual movement of arbitrary geometry during the course of the simulation. “PowerFLOW is an inherently transient simulator,” remarked James Hoch, Exa’s Vice President of Software Development. “Updating the position of the geometry at each time-step is a natural extension of the core technology, resulting in very accurate prediction of the fluid flow in and around rotating geometry.”

PowerFLOW 4.2 Overview
This newest Exa release adds functionality that not only extends the simulation capabilities of PowerFLOW, but when coupled with complementary products such as PowerTHERM® and PowerACOUSTICS™ also improves aerodynamic, aeroacoustic and thermal results.

• True Rotating Geometry. PowerFLOW 4.2 further extends Exa’s leadership in simulation technology by offering the first practical and accurate simulation of the actual movement of rotating components. True rotating geometry enables prediction of the noise and performance of HVAC and cooling fans. It also improves accuracy for any application that has rotating components, especially those transient in nature such as brake cooling and wheel aerodynamics. PowerFLOW 4.2 offers an easy-to-use case setup for true rotating geometry as well as built-in support for visualization of results showing the geometry rotating.

• Long Term Transient Simulations. PowerFLOW 4.2, an inherently transient solver, coupled with Exa’s PowerTHERM, now allows for the simulation of minutes or even hours of real time for the accurate prediction of critical thermal cool-down conditions such as key-off and soak.

• Accuracy. In addition to the accuracy benefits realized with true rotating geometry, PowerFLOW 4.2 offers an improved turbulent thermal wall model and porous media physics for enhanced precision and robustness in these extremely complex simulations.

• Turnaround Time. Exa continually works to streamline the engineering simulation and analysis process. Exa has now published validated design study best practices using reduced resolution runs that dramatically reduce the time and compute resources required. With PowerFLOW 4.2 extensive turnaround time enhancements are included, such as: application specific case templates—a sophisticated automated case setup capability which allows capture and re-use of company best practices; enhanced cluster/queuing support; automatic coarse-to-fine seeding capabilities; and real-time volume visualization.
