Fast AND Reliable CFD Solutions

The pressures of global competition, complex requirements and shorter development schedules are forcing CFD engineers to do more in less time — without sacrificing accuracy. 

Accurate results help to prevent over-engineering along with its embedded costs. With high-fidelity CFD results in hand, engineers can design within smaller safety factors, which can ultimately reduce cost of a product or process. Conversely, poor-quality CFD results can lead to incorrect design specifications and increased development time. Accuracy and reliability of fluid flow simulation builds confidence that the solution will operate as intended, allowing shorter design cycles and quicker time to market.

The simultaneous pursuit of CFD speed and accuracy is a critical dilemma that can seem next to impossible. Engineers sometimes believe they must choose one over the other. But ANSYS has incorporated both with its CFD product suite, without compromise. By reducing overall time to reliable solutions, ANSYS fluid dynamics software enables organizations to do more in less time with fewer resources than ever before.

The suite offers powerful geometry tools with bidirectional parametric CAD connectivity and direct modeling capabilities, Furthermore, it provides complete meshing flexibility, from highly automated to user-defined meshing. For many applications, ANSYS Meshing within in the ANSYS Workbench platform is fully automated and produces high-quality meshes suited for capturing important flow features (such as flow separation, mixing and recirculation). Specific applications, such as turbomachinery and external aerodynamics, benefit from advanced capabilities. The products deliver advanced CAD/geometry readers and repair tools that allow users to quickly move to geometry-tolerant meshers and produce high-quality volume or surface meshes with minimal effort.

ANSYS Meshing capabilities enable large high-quality meshes of complex models for accurate CFD results.

ANSYS fluid dynamics software contains sophisticated numerics and robust solvers to ensure fast and accurate results for a nearly limitless range of flows, including (among others):

  • Laminar to transitional to turbulent
  • Subsonic to transonic to supersonic
  • Single phase to free surfaces to multiphase
  • Inviscid to non-Newtonian to visco-elastic
  • Single species to multiple species to reacting species
  • Forced convection to natural convection

Advanced solver and HPC technologies leverage the latest software and hardware advancements to arrive at an accurate solution fast.

Embedded large eddy simulation (LES) capability combines different turbulent flow models to achieve higher-accuracy results in reduced amounts of time.

To increase workflow throughput, ANSYS fluid dynamics software allows users to automatically investigate multiple, parametric design variations — all without complex programming. This enables teams to optimize workflow by automatically propagating changes in geometry, meshing and physics without any manual rework. The ANSYS integrated solution for Design of Experiments promotes easily analysis of thousands of data points in a single user environment. Other integrated tools help a user to understand which parameters a design is most sensitive to as well as to determine which design parameters require the tightest control. 

Integrated tools for design optimization and Six Sigma analysis are also available.

Design exploration and optimization for fluid dynamics simulation can be set up easily. The entire workflow is visible at a glance, even for analyses involving Design of Experiments and goal-driven optimization.

To meet an organization's present and future simulation and workflow process requirement, ANSYS fluid dynamics software is readily customizable and extensible. Users can implement their own specialty physics model, and the user environment can be readily customized and scripted for ensuring established best practices and further workflow automation.

To ensure that established fluid simulation best practices are followed, input panels can be defined that contain application- or company-specific terminology.
