Test vs analysis? Better yet, both!

Most of you know us as your ANSYS software and service provider. While ANSYS certainly represents the focus of our business, it’s not all that we do. Another way we serve our clients is through our physical testing team.

Our physical test team has worked not only across North America, but throughout Europe and Asia and with many industry sectors. For example, our testing experts were key in developing and deploying a digital twin model employed on a turbine for a Middle Eastern power plant.

Given that most of you work mainly with simulation, why are we bringing testing to your attention?

A goal of simulation is to reduce physical prototype testing, but physical testing still has a role in product development and failure investigations. In fact, physical models can work hand-in-hand with simulation in many cases.

How to Extract Moments of Inertia for Point Masses … and Simplify Your Model

One question often facing engineers performing any type of simulation analysis is, “How can I simplify my model and still get accurate results?”

A case in point for FEA analyses: When engineers have a large assembly with multiple parts but are interested in the simulation results of only one of the parts, only the part of interest needs to be fully modeled and meshed. The remaining parts can be reduced to a point mass where their effects are accounted for, but they are not fully meshed. As a result, this approach significantly reduces the size of the overall model as well as the solution time. In other words, it is a much smaller model to solve.

ANSYS Plans to Acquire Livermore Software Technology Corporation—What that Means for You

LS-DYNA truck crashOn September 11, 2019, ANSYS, Inc. announced plans to acquire Livermore Software Technology Corporation (LSTC), the developers of LS-DYNA. Here’s what that means for you, our customers.

When the acquisition is complete, LS-DYNA will be forever included in the ANSYS software suite. That means that you’ll always have access to LS-DYNA’s explicit dynamics and other FEA analysis capabilities, including:

  • Drop tests
  • Metal forming processes
  • Explosions
  • Impacts
    • car crashes, including the vehicle structure and all components and a variety of materials (plastics, fabric, foam)
    • bird strikes, helpful in aerospace companies
    • blade containment
    • sports equipment such as golf clubs and football helmets

“ANSYS LS-DYNA is one of the premier explicit solvers. We have been relying on it regularly for various analyses such as drop test, metal forming, projectile impact, and vehicle crash simulations,” says Butch Vision, SimuTech VP of Engineering.

Latest ANSYS release 2019 R3 offers coupled field analysis, Granta MDS, and more

The latest ANSYS® release, 2019 R3, offers several new features our clients might be interested in.

ANSYS 2019 R3 release ANSYS Software - 3D Design3-D Design

Discovery™ Live now has an interactive topology optimization tool that allows for generative design and improved functionality for simulations, including mass flow outlets and time-varying inputs.

SpaceClaim® now offers automatic surface reconstruction from faceted geometry, converting triangle-based models into CAD models for generative design and reverse engineering. Visualizations have improved, too.

Finally, support for structural beams, linear buckling capabilities, and physics-aware meshing enhancements are now available in Discovery™ AIM®.

 

ANSYS Software - Additive ManufacturingAdditive Manufacturing

With a new build processor, you can export a build file directly to an AM machine with ANSYS Additive Prep.

 

ANSYS Software - ElectromagneticsElectromagnetics

Clients using ANSYS® HFSS™, ANSYS® Maxwell®, and ANSYS® Q3D Extractor® have the benefits of high-powered computing from the ANSYS Cloud. With new capabilities for modeling and post-processing, ANSYS HFSS and ANSYS HFSS SBR+ provide even better autonomous system simulation for radar cross-section scenarios. And ANSYS HFSS SBR+ now offers creeping wave physics.

How to Borrow ANSYS Licenses for Maximum Productivity

ANSYS Borrow UtilityMost of our customers, especially medium-to-large organizations, keep ANSYS® software licenses on a corporate network server. This network-enabled (floating) licensing allows engineers across the organization to have access when they need it.

Each organization has different needs for ANSYS products. One organization might be involved exclusively with structural analyses, so they need multiple seats of ANSYS® Mechanical™ Workbench™. Another organization might be focused on electric motor design and need a mix of ANSYS Mechanical Workbench, ANSYS® Fluent®, and ANSYS® Maxwell®.

Sharing licenses across a corporate network works great, but everyone must be connected to the network. A license is “checked out” when an ANSYS session is started up and “checked in” once the session is closed. This “checked out/in” process is controlled by the ANSYS License Manager utility on the corporate network.

However, an engineer may need access to a license while he or she is away from the office (e.g traveling to a customer site). The engineer can then “borrow” or “check out” a license for a certain period of time, but that license it is not available to the other engineers during that extended period.
