Engineers are under pressure to optimize designs during ever-shrinking development cycles. In response, computer-aided engineering (CAE) tools — like the latest enhancements in the ANSYS 19.2 release — now facilitate faster and easier-to-use workflows.
New ANSYS Fluent Task-based Workflow with Mosaic-enabled Meshing
A Mosaic mesh of an F1 wing connects hexahedral elements in the bulk and isotropic elements in the boundary, using polyhedral elements.
Engineers using ANSYS Fluent can now create more accurate computational fluid dynamics (CFD) simulations.
Fluent’s single-window, task-based workflow for watertight geometries dramatically reduces the time to set up and run CFD simulations.
This new workflow incorporates best practices to help prevent engineers from second-guessing themselves as they set up complex CFD models.
For instance, the workflow guides the engineer through the simulation process and best practices. It does this by reducing the engineer’s options to those that are relevant at each point in the process. Engineers will see only the turbulence models, meshing options and inputs that are relevant to the task at hand.
CFD engineers should also take note of new Mosaic meshing in ANSYS 19.2. This technology automatically combines any boundary layer mesh with high-quality polyhedral meshes for fast and accurate flow resolution.
In a benchmark study, the Mosaic mesh had fewer cells, required one-third the memory and delivered a solution two-times faster than a polyhedral mesh of similar accuracy.
ANSYS 19.2 Reduces Time to Market for Designers
A parameter study that is optimizing biker separation to reduce drag.
ANSYS Discovery Live has also seen a significant workflow improvement thanks to 19.2’s real-time parameter studies.
While Discovery Live has always been lightning fast with its simulations, all parameter changes were made manually. These manual parameter inputs slowed down development.
Now, design engineers can automate the exploration of their products’ design space using parameter studies. With this information, they can quickly assess the trends and trade-offs between design goals.
ANSYS 19.2 also advances the workflow for physics-aware meshing in ANSYS Discovery AIM. This improvement identifies high-stress concentrations faster than before.
Safety Assessment Workflows for Autonomous Vehicle Development
VREXPERIENCE gives engineers the ability to validate autonomous vehicles and ADAS features in a customizable virtual environment over millions of miles.
The release offers a series of tools and workflow improvements for to ensure the safety of advanced driver-assistance systems (ADAS) and autonomous vehicles.
For instance, the recent acquisition of OPTIS now brings ANSYS VRXPERIENCE into our portfolio.
With this tool, engineers can validate automotive safety features in a virtual world.
VREXPERIENCE offers engineers an expedient way to test safety features for autonomous vehicles over millions of virtual miles. These virtual drives can be customized to various roads, environments, weather, traffic and pedestrian conditions.
The release also introduces ANSYS SPEOS, a tool that will help engineers set up optical simulations. It empowers engineers to test the optical performance of LiDAR, lights and cameras within a system.
This means that engineers can use SPEOS and VREXPERIENCE to assess the optical sensors of their autonomous vehicles within a simulated world.
Workflow improvements to ANSYS medini analyze will also expediate the development of autonomous vehicles. These enhancements will help semiconductor companies ensure the safety of ADAS and autonomous systems to meet ISO 26262 Standards. These upgrades also streamline functional safety analyses, so semiconductor companies can get to market in half the time. Engineers using medini analyze will also be able to export a required safety analysis.

ANSYS 19.2 also includes additions to the ANSYS SCADE Suite’s embedded software design workflows. These tools will make it faster to develop and verify safety-critical embedded code. This is key for any engineer designing a complete safety system for ADAS or autonomous vehicles.
In addition, the release streamlines SCADE’s connectivity to both Simulink and Jama software.
Workflow Upgrades for Multiphysics Simulations Increase Speed and Usability
Another speed boost is available for engineers working on two-way coupled simulations.
ANSYS 19.2 introduces System Coupling 2.0, which improves data mapping and co-simulations. These upgrades will better leverage the speed of high-performance computing (HPC).
The release also enhances text-driven workflows that control multiphysics simulations. This will make it easier for engineers to start and restart a simulation that assesses the interactions between a fluid and a structure.
Structural Workflows for Design Optimization
Turbine designed using inverse analysis
ANSYS 19.2 offers workflows to help optimize structural designs.
One example is the inverse analysis. This tool helps engineers determine the unloaded shape of a component so that, when loaded, they get the shape they expected.
Engineers can also take advantage of a new material design feature. This tool allows engineers to create detailed models of materials and calculate equivalent properties for larger-scale simulations.
Additive manufacturing (AM) experts will benefit from ANSYS 19.2’s new physics-driven lattice optimization function. Additional loading options and manufacturing constraints for topology optimization are also included in the release.
Faster Electronic Design Workflows
Finally, the release offers workflow enhancements to the electromagnetic suite. The suite now includes advancements to its multichannel radar system simulations. This upgrade comes in the form of a lightweight geometry modeler that hastens meshing and simulation processing.
Other electromagnetic improvements in 19.2 include:
- New capabilities in ANSYS Icepack to compute the thermal impact of multiple electromagnetic loss connections.
- A stackup wizard in ANSYS SIwave that allows for easy definition and exploration of printed circuit board (PCB) stackup layers and impedances.
