All engineering simulation starts with geometry to represent the design, be it a solid component for a structural analysis or the air volume for a fluid or electromagnetic study. The engineer either has geometry that has been produced in a computer-aided design (CAD) system or builds the geometry from scratch. ANSYS DesignModeler software is the gateway to geometry handling for an ANSYS analysis.
CAD models are often designed for manufacturing use and not for simulation. Using CAD models results in a complex geometry that includes details not needed for simulation, such as logos and other small features. Simulating such a fully detailed model will increase solver run times. It can be more efficient to spend a short time removing these details to reduce the total run time by hours or days. ANSYS DesignModeler features that reduce model complexity include:
- Fillet removal
- Symmetry division
- Fluid domain extraction
- Small surface detection and removal
- Cavity fill
- Geometry repair
ANSYS DesignModeler software has connections to all major CAD systems, allowing seamless transfer of existing data including parameters. For example, if your CAD model has a parameter that defines the wall thickness of a part, this can be exposed in ANSYS DesignModeler. You can then adjust the parameter and update the design. Any feature removal or simplification is maintained. This results in rapid turnaround of any design changes and updates.
ANSYS DesignModeler technology also provides powerful tools for construction of geometry from the ground up. Using familiar solid modeling operations, a complex model can be produced. Built on the Parasolids kernel which means the geometry engine is robust and conforms to industry standards. 2-D sketches can be extruded into 3-D solids and then modified with Boolean operations. A construction history is recorded during the creation of the geometry, allowing the user to make changes and then update the design.
Whether importing an existing CAD model or building your own, the ANSYS DesignModeler product is fully parametric. Combine this with parametric meshing and parametric solver setup within the ANSYS Workbench platform and you can use the same geometry for multiple design variations.
ANSYS SpaceClaim Direct Modeler
ANSYS SpaceClaim Direct Modeler (ANSYS SCDM) brings you a new way to manipulate your CAD models. The model becomes completely dynamic, allowing you to move, stretch, add and remove with mouse movements. All changes to the CAD model occur in real time on the screen so you have instant feedback on your design.
This functionality will work with existing CAD from 3rd party systems as well as CAD that you have build directly within ANSYS SCDM. The user can also dimension these changes, resulting in a parametric CAD model from non-parametric imports. For example, an IGES file can be imported into ANSYS SCDM and moved as if it was fully parametric.
This type of geometry creation and manipulation is known as Direct Modeling and ANSYS SCDM connects to ANSYS Workbench allowing rapid design changes and updated simulation results. Up front design optimization becomes quicker and simpler with ANSYS SCDM.
With direct interfaces to all major computer-aided design (CAD) systems, support of additional readers and translators, and an integrated geometry modeler exclusively focused on analysis, ANSYS offers the most comprehensive geometry handling solutions for engineering simulation in an integrated environment.
ANSYS geometry handling solutions include best-in-class CAD integration technology in an industry-leading, CAD-neutral CAE integration environment. This provides direct, associative, bidirectional interfaces with all major CAD systems.
The state-of-the-art ANSYS CAD integration solutions include options for smart and selective updates of CAD parts. ANSYS CAD interfaces also include a Named Selection Manager. The Named Selection Manager can be used to create custom attributes within CAD systems and use them directly in ANSYS applications for modeling, meshing and analysis.
With geometry integration solutions from ANSYS, you can use your existing, native CAD geometry directly, without translation to IGES or other intermediate geometry formats. ANSYS has offered native, bidirectional integration with the most popular CAD systems for more than 10 years. ANSYS also provides integration directly into the CAD menu bar, making it simple to launch world-class ANSYS simulation technologies directly from your CAD system.
CFD simulations don’t end with the fluid flow prediction. To benefit from the prediction requires post-processing that gives users complete insight into their fluid dynamics simulation results. ANSYS CFD-Post, the common post-processor for all ANSYS fluid dynamics products, gives users everything they need to visualize and analyze their results.
Within a modern and intuitive user interface, ANSYS CFD-Post sets no limits on creativity when generating powerful images to illustrate the flow in any desired level of detail. From vector plots and streamlines to vortex cores and flow animations, ANSYS CFD-Post provides users all the tools they need to produce insightful solution visualizations, including 3D images viewable by anyone with the freely distributable 3D viewer. These high-quality visuals are invaluable in communicating results to colleagues and customers, helping to explain and understand complex flow phenomena.
High-end graphical post-processing is only one part of ANSYS CFD-Post; its quantitative post-processing abilities are at least as important and powerful. With the functions of ANSYS CFD-Post at their fingertips, users can quickly get all the data they need out of their calculation: weighted averages, mass flows, forces, maximum/minimum values, and many more functions enable precise analysis of the CFD results. Add tabulated results presentation, chart plotting, special turbomachinery functionality, and automatic report generation, and there is virtually no limit to the post-processing possibilities in ANSYS CFD-Post.
The final touch is automation: Users can easily create macros, for example by recording the interactive steps in a session file for replay and re-use with similar cases, and create images, charts, tables, and reports automatically for different simulation results. CFD-Post can also be run completely in batch mode, for fully automated processes and integration in optimization.

ANSYS HPC for High-Fidelity Insight and Design Team Productivity
ANSYS HPC delivers cross-physics parallel processing capability for the full spectrum of ANSYS simulation software, supporting structural, fluids, thermal, and electromagnetic simulations in a single HPC solution. Buy once, deploy once, and get the most from your HPC investment.
Parallel processing with ANSYS HPC allows you to consider higher-fidelity models – including more geometric detail, larger systems, and more complex physics. 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, you can gain confidence in your design and ensure that your product will succeed in the market.
ANSYS HPC also increases throughput by speeding up turn-around time for individual simulations. This enables you to consider multiple design ideas and make the right design decisions early in the design cycle. Using ANSYS HPC you therefore make your engineering staff, and your product development process, more productive and efficient. With ANSYS HPC, you won’t be waiting for answers or making design decisions based on single point solutions.
