ANSYS 18.1 expands pervasive engineering simulation

ANSYS is continuing to build upon the digital exploration and digital prototyping capabilities released in ANSYS 18 with the release of ANSYS 18.1. The software is said to enable organisations to simulate more upfront, limit costly late-stage design changes, and bring their innovative products to market faster and easier.

“Products are becoming smarter and organisations are adopting simulation across the entire lifecycle to digitally gain insight into product choices at every stage of the process – a growing trend we call pervasive engineering simulation,” said Mark Hindsbo, ANSYS general manager. “This latest release continues the tradition of having the most complete and accurate solution portfolio in the industry, so our customers can trust the simulation results to conquer the toughest design challenges and accelerate product innovation.”

In the fluids suite, ANSYS 18.1 is said to deliver faster, higher fidelity – enabling users to simulate more quickly and accurately. Users will benefit from greater flexibility setting up periodic boundaries to deliver high fidelity results up to nine times faster for in-cylinder diesel simulations.

In the structures suite, new capabilities have been added within its topology optimisation technology to analyse complex materials and optimise designs making it easier for organisations to manufacture products. Users can now combine load cases from modal and static structural analysis to look at designs that meet frequency and structural requirements. Designers will benefit from the new optimisation constraint capabilities, giving them more control over manufacturing constraints to help ensure the most optimised designs are built.

Designers will also benefit from new significant capabilities in the electromagnetics suite. Noise-vibration-harshness (NVH) analysis has been expanded to include both magnetostriction and induced magnetostriction effects. That enhances the accuracy of NVH studies of electrical machines and transformers.

Also, ANSYS 18.1 is enhanced with new a characteristic mode analysis solver. This enables electronics designers to study antenna placement and antenna synthesis for devices such as a smart watch, mobile phones and Internet of Things devices. The characteristic mode analysis accurately predicts the fundamental resonance characteristics of an antenna or the platform to which they are mounted, allowing engineers to choose the optimal location for the antenna on the device and synthesise the desired antenna pattern.

ANSYS AIM further expands the landscape for digital exploration in ANSYS 18.1 with enhancements across all physics. AIM now supports fluid simulations through porous media, such as filters, perforated plates, packed beds and flow distributors. Engineers can now explore more fluid designs under a variety of circumstances, while not sacrificing speed and ease of use simulations. Support for bi-linear isotropic hardening plasticity enables users to achieve more accurate results in designs where material yield overloading is a concern. AIM's one-way thermal-magnetic coupling is claimed to create accurate designs for electromechanical products operating at elevated temperatures easier.

ANSYS SpaceClaim builds upon its powerful optimisation tools for additive manufacturing in ANSYS 18.1. Enhanced infill structures capabilities enable users to increase design strength without sacrificing weight in their product design. This latest release also brings the powerful scripting functionality and interactive features to the SpaceClaim user interface. Now designers can create scripts and provide inputs at various stages of the design process. Improvements have also been made to the shared topology method giving users a more robust transferring of connections between components – saving them time in the design process.
