Common Workflow for High Productivity Common Workflow for High Productivity

The ANSYS CFD product provides access to both ANSYS FLUENT and ANSYS CFX software. Thanks to ANSYS Workbench technology, these two well-known products share a common workflow. CAD connectivity, geometry modeling, meshing and post-processing are shared by both products.

Engineers can use the familiar ANSYS Workbench tools to perform parametric analysis and design optimization. ANSYS CFD works smoothly with pre-processing software such as ANSYS DesignModeler, ANSYS Meshing and ANSYS DesignXplorer tools. This combination greatly reduces the learning curve for those who want to be able to use both CFD products and other ANSYS solutions. The ANSYS Workbench platform integrates a large variety of technology choices tailored to meet individual needs, while ensuring interoperability and a clear future upgrade path.

Powerful & Scalable High-Performance Computing Powerful & Scalable High-Performance Computing

ANSYS fluid dynamics provides powerful and scalable high-performance computing (HPC) options. Parallel processing with ANSYS CFD HPC allows users to consider higher-fidelity CFD models — including more geometric detail, larger systems (such as a full 360-degree blade passage rather than a single blade one), and more complex physics (for example, unsteady turbulence rather than steady turbulencel). The result is enhanced insight into product performance — insight that can’t be gained any other way. This detailed understanding can yield enormous business benefits, revealing design issues that might lead to product failure or troubleshooting delays. Using HPC to understand detailed product behavior, users can gain confidence in their designs and help ensure that the product will succeed in the market.

ANSYS CFD HPC  increases throughput by speeding up turn-around time for individual CFD simulations. This enables engineers to consider multiple design ideas and make the right design decisions early in the design cycle. Using ANSYS CFD HPC makes the engineering staff, and the entire product development process, more productive and efficient. 

ANSYS CFD technology incorporates optimization for the latest multi-core processors. It benefits greatly from recent improvements in processor architecture, algorithms for model partitioning, combined with optimized communications and load balancing between processors. ANSYS CFD HPC is easy to use and works exceptionally well from multi-core desktop workstations to high-end HPC clusters. Linear scalability has been shown on systems with more than 1,000 processors.
