Better, Faster Prep and Meshing with ANSYS CFD
For computational fluid dynamics (CFD) simulations to limit, or potentially replace, physical prototyping and testing, fidelity and accuracy are critical. In the past, high-fidelity, high-accuracy results came with a price. Complex geometries required hours of manual effort for model cleanup and mesh preparation. Failing to execute these steps often skewed the results in undetectable ways.
With ANSYS CFD, you’ll never compromise on results. Building on a legacy of innovative meshing tools, including ANSYS Meshing, ANSYS ICEM CFD, GAMBIT, ANSYS TGrid, ANSYS Fluent meshing and ANSYS TurboGrid, our newly introduced capabilities reduce hands-on time and speed time-to-results, without compromising mesh quality or solution accuracy.
Innovations Speed CFD Simulations Allowing Engineers to Achieve Fast, Accurate Results
Mosaic Meshing Technology
ANSYS Fluent meshing now includes a unique patent-pending Mosaic technology that automatically combines disparate boundary layer mesh types using high-quality polyhedral meshes for faster and more accurate flow resolution.
Fluent Task Based Workflow for Prep and Meshing
Fluent’s task-based workflow helps engineers make the best possible choices for more accurate simulations in less time and facilitates the preparation and meshing of “watertight geometries.” It guides the user through a streamlined decision-making process, in which only the most relevant options are presented for consideration. Benchmark simulations show users complete the workflow with 70 percent fewer clicks and 50 percent less hands-on time
PUMA: Polyhedral Unstructured Mesh Adaptation
Capturing the fine details in free surface flows and combustion simulations requires an extremely fine polyhedral mesh. In the past, automatic adaptive mesh refinement was not possible for polyhedral cells, resulting in extremely long solve times. Now, patented, polyhedral unstructured mesh adaptation (PUMA) in Fluent automatically refines the polyhedral mesh to resolve fine details, while leaving coarser mesh in place. As a result, engineers can get the accuracy they need — without the wait.
PUMA technology automatically refines polyhedral mesh to capture splash details, while leaving courser mesh in place for faster solve times.
Direct Modeling Speeds Prep
To calculate the right solution, it is important to model the right geometry. Complex models provided for simulation are often prepared by multiple designers, sometimes working on different systems. As a result, when models are brought together for simulation they are rarely complete For this stage, ANSYS SpaceClaim is the ideal partner to inspect and rectify major faults in the geometry that simply cannot be glossed over. Unlike typical bottoms-up CAD systems, ANSYS SpaceClaim is a direct modeler and can be used to move whole components, close off regions or shrink large gaps. ANSYS SpaceClaim is fast and interactive, and it provides the perfect environment for rapid correction of complex geometries.
