Ansys Motion Adds Multibody Dynamics to the Ansys Portfolio

Ansys 2019 R1 will include a new product line — Ansys Motion.

MBD simulation shows how a car handles and swerves.

The new product line is a third-generation MBD solver offering a full suite of dynamics capabilities for rigid and flexible bodies. Ansys Motion also has an extensive range of application-based toolkits.

The creation of Ansys Motion stems from a decade of development in partnership with South Korea’s Virtual Motion.

A New Ansys Fluent Experience Makes CFD Intuitive

As an example, engineers can now input equations as boundary conditions without coding or creating a user-defined function (UDF).

Engineers can also try a beta version of a fault-tolerant task-based workflow. The workflow helps engineers mesh dirty, non-watertight geometries.

Other improvements to Fluent also aim to simplify or accelerate the simulation process, such as:

• The ability to generate a mesh seven times faster using parallel processing — without a high-performance computing (HPC) license.
• The generalized k-omega (GEKO) turbulence modeling that can be fine-tuned to specific simulations.

Ansys Mechanical Nearly Doubles Its Speed

Ansys 2019 R1 includes improvements in the Ansys Mechanical suite that will accelerate product development.

Ansys Mechanical’s new ability to split contact regions means that the finite element analysis (FEA) solver can scale more efficiently when solving assemblies.

This engine assembly is split into regions to help distribute the computational load of the simulation.

Since the software can split contact regions, it can partition and distribute the computational load more evenly between compute cores.

So, how much can contact splitting speed up development? Tests show that a model with 9.1 million degrees of freedom (DOF) running on 256 cores can now be solved 85.8 times in a single workday. Without contact splitting, the same model could be solved 46.3 times.

The speed-accelerating improvements will benefit many engineers — even if they don’t have access to 256 cores. Richard Mitchell, lead product marketing manager at Ansys, says: “We can now make Ansys Mechanical run on 3,000 cores. To scale like this, every bit of code has to be as fast as possible. So, this way, all users benefit from a faster solver experience.”

Ansys 2019 R1 will have other Mechanical improvements, including:

• Topology optimization tools that lightweight shell geometry.
• Topology optimization tools that maximize heat transfer.

Determine the Optimal Settings for Metal Additive Manufacturing

These simulations are based on a series of printer settings, including (but not limited to):

• Material selection.
• Baseplate temperature.
• Layer thickness.

Another improvement to Additive Suite is a new layered tetrahedral meshing option in Ansys Workbench Additive.

Layered tetrahedral meshing makes it easier to represent the geometry of a part without increasing the model size. This helps engineers represent the fine-featured geometry that additive manufactured parts are known for — such as narrow channels and thin walls.

Topology Optimization Added to Ansys Discovery Live

Once Discovery Live creates the part, engineers can set up a simulation to learn — in real time — how to optimize it further.

Some beta features have also been added to Ansys Discovery SpaceClaim to speed up product development. These features make it easier to create and parameterize models, by:

• Controlling 3D models from the sketches used to create them.
• Updating models to sketch dimensions via the scripting menu.

Finally, Ansys Discovery AIM has expanded its physics capabilities with a new random vibration solution. This solution helps engineers determine the likelihood that a design will experience a certain displacement or stress when it’s exposed to a range of loads.

Simulation Tools that Ensure the Reliability of Electronics

Trends like the internet of things (IoT), electrification and autonomous driving are pressuring engineers to add more electronics to every product. As a result, electronics reliability is more important than ever.

To address this need, Ansys 2019 R1 includes an electromigration analysis workflow for Ansys SIwave and an EMI Scanner for Ansys SIwave and Ansys HFSS.

EMI Scanner checks if a circuit board’s design follows engineering best practices.

The EMI Scanner takes a few seconds to ensure that a circuit board follows standard engineering design rules. This way, engineers don’t waste precious computational time simulating a circuit board that is bound to fail.

Additionally, the electromigration analysis workflow helps engineers determine the mean time to failure for chips and advanced electronics packages. Since electronics are becoming smaller, current densities are rising — increasing the risk of electromigration. Over time, electromigration makes copper wires brittle. The electromigration analysis tool ensures these wires will perform throughout the service life of the product.

Ansys 2019 R1 also includes electronics simulation improvements for the automotive sector, including:

• Noise, vibration and harshness (NVH) multiphysics workflow to develop quiet electronic motors in Ansys Workbench.
• Antenna blockage study to assess interactions between automotive radar and car bumpers in Ansys HFSS SBR+.

New Ansys SCADE Capabilities for the Automotive Sector

Ansys SCADE can generate target-independent parallel code from any legacy application.

Other industry improvements to Ansys SCADE, include:

• Faster and simpler AUTOSAR compliance workflows that develop model-based systems.
• A Test Model Coverage tool that checks for DO-178C and DO-331 errors.

Functional Safety Analysis Workflow for Civil Airborne Systems

Functional safety engineers will notice product development improvements in Ansys 2019 R1. For instance, Ansys medini analyze provides engineers with a systematic workflow, in accordance with DO-178C, to assess:

• Aircraft system functions.
• Failure conditions.
• Safety requirements.

Ansys medini analyze provides engineers with a systematic workflow, in accordance to DO-178C.

The release also includes a new safety assessment process that is compliant with ARP4761 — Guidelines and Methods for Conducting the Safety Assessment Process on Civil Airborne Systems and Equipment.

Additionally, engineers will benefit from a new editor that calculates and visualizes function dependencies and allocation relations.

Ansys Twin Builder Generates Actionable Insights for Predictive Maintenance

Ansys Twin Builder is a simulation solution that builds, validates and deploys digital twins.

Twin builder code controlling a digital twin

Twin Builder helps optimize a product’s performance while it is in operation. These performance improvements include:

• Root-cause analysis.
• Predictive maintenance.
• Control strategy analysis.

The latest release of Twin Builder supports runtime generation capabilities. These capabilities enable engineers to collect, process and interpret data from industrial internet of things (IIoT) platforms. These platforms include SAP Leonardo IoT, PTC ThingWorx and more.

Additionally, Ansys 2019 R1 introduces a dynamic reduced-order model (ROM) builder. The ROM builder is a machine learning tool that enables engineers to simplify and import complex dynamic models into Twin Builder. The simplification process preserves the features and accuracy of simulations while enhancing their speed.

In addition, Twin Builder incorporates IEEE VHDL-2008 encryption, which helps to protect intellectual property. The encryption allows engineer to encode, decode and exchange Twin Builder models without exposing their internal workings.

Optical Simulation Improvements Focus on the Automotive Sector

The Speos human vision simulation model has also been improved in Ansys 2019 R1. The new model takes pupil diameter and low luminance levels into account when forming an optical simulation.

The human vision simulation model helps automotive engineers optimize the look of a car’s interior and HUD with respect to the human eye.
