An Engineer’s Guide to Materials Calibration when Modelling Bulk Solids

Predicting the bulk solid’s behaviour and extracting information which cannot easily be measured experimentally are key benefits of Discrete Element Method (DEM) simulations, such as Ansys Rocky DEM. However, the quality of the prediction depends on the calibration of the simulation. This guest blog by Dr Daniel Grasser, Consulting Engineer at TUNRA Bulk Solids, Newcastle (Australia) introduces guidelines for the Discrete Element Method calibration in the context of bulk solids handling and mining/minerals.

Managing Your PTC Desktop Product Licenses

PTC has updated its desktop products license management system for applications like Creo, Mathcad, and more — covering both floating and node-locked licenses. In this article we have provided the key takeaways from a recent webinar delivered by Ben Muston, Senior Application Engineer at LEAP who walks through how license administrators can request, retrieve and manage licenses, including host changes, to help ensure an optimal setup for all users within your team.

Expert Tips on tuning the GEKO turbulence model

This article answers the question, “What is special about the GEKO model compared with all other two equation RANS models?” The result of the decades of experience that Dr. Florian Menter has acquired through his vast experience of turbulence modelling at NASA and Ansys, the GEKO model is very much the culmination of a life’s work on improving turbulence models to make them what he calls “industrial strength”. Read on to learn more.

Fluid-structure interaction simulation of wave overtopping flow and vegetation for coastal hazard mitigation

Climate change is increasing the exposure of communities to coastal hazards and traditional solutions, such as seawalls or revetments, can have a high financial, social and environmental cost. As a result, nature-based solutions are encouraged in coastal policy. This guest article by University of Auckland’s Joshua Bagg, Mark Battley, Colin Whittaker and Tom Shand describes their unique research aimed to investigate the interaction between salt marsh grass and wave overtopping flow using Ansys Fluent and Ansys Rocky to inform the design of nature-based solutions.

Automating Annotations and Customising Output in Creo

Creo provides automated annotation features that enhance productivity and improve accuracy in the design and documentation processes. By reducing the manual effort associated with annotation tasks and ensuring consistency across models and documentation, these features support a more efficient workflow for engineers and designers. As part of our Creo Best-Practices webinar series, Ben Muston, Senior Application Engineer at LEAP recently covered these features in depth, and here we have summarised the key take aways and provided the video hightlights.

25th Anniversary of UNSW Redback Racing – A look back at Formula-SAE Aerodynamics Strategies

Founded in 2000, The University of New South Wales (UNSW) Formula SAE Team, UNSW Redback Racing has continued year on year to design, build and race in the Formula SAE Australasia competition. With each car, the team strives for improvement and innovation, building on previous designs and advancing their knowledge into the future. An important part of this process is the use of Ansys Simulation for their Aerodynamics package and in this article, the team outlines their aerodynamics simulation strategy, explaining how they got to their current design, and their plans for the future.

Applying Tangential Pressure in Ansys Mechanical – Transfer Chutes

Transfer chutes are very commonly used in bulk material processing and handling scenarios, particularly for bulk granular materials. When analysing the structural performance of a transfer chute, it’s important to consider how the flow of material will impact your design, and to then quickly evaluate the structural performance of the design under load. Whilst it’s straightforward to account for the normal component of pressure in a design, the tangential pressure is a trickier load to setup. In this blog, we’ll investigate how you can setup pressure loads to capture tangential pressures for a variety of transfer chute geometries.

Photorealism when rendering everyday objects – Edward Poropat on LEAP’s KeyShot Challenge

Among the many creative and diverse entries to our 2025 KeyShot Challenge competition were two submitted by Edward Poropat, Industrial Designer at Alchin Long Group that caught our eye. In this article, Edward provides some background on his two submissions, explaining each design and the processes he went through to create his fantastic renders.

Drawing Formats, Templates, and Best Practices in Creo

In this post we show you how to set your team up for success with standardised drawing templates and formats in Creo. As part of our Creo Best-Practices webinar series, Ben Muston, Senior Application Engineer at LEAP recently tackled drawing formats and templates, covering title blocks, custom symbols, revision tables, repeat regions, and how to drive consistency across 2D and MBD-enabled drawings for efficient documentation processes.

NAFEMS Discovery Benchmark Series – Part 4: Axisymmetric Geometries

Our exploration of Ansys Discovery’s capabilities now shifts from general 3D geometries to a specialised yet widely encountered case: axisymmetry. Many essential components such as pipes, flanges and pressure vessels, exhibit rotational symmetry. In this section, we examine Discovery’s performance on axisymmetric problems using two established NAFEMS benchmarks, LE7 and LE8 – read on to see the results.
