Ansys Rocky for Slurry Flows

Understanding slurry flows is crucial for applications such as mining and mineral processing, chemical manufacturing, wastewater treatment, agriculture and many more. Ansys Rocky DEM can help to accurately predict the behavious of a slurry by simulating the size and shape of the solid particles, the types of solids present, the viscosity of the liquid and the concentration of the solids in the liquid.

This article explains how Rocky DEM empowers you to model slurry flows – from mills to open channels – and gain a clear understanding of particle-fluid interactions with remarkable accuracy.

Advanced Features of Ansys Rocky DEM for Next-Level Simulation

This article provides a dive deep into the cutting-edge capabilities of Ansys Rocky DEM, showcasing how advanced features like OptiSLang integration, robust API capabilities, and Multi-GPU acceleration can transform your simulation experience.

Whether you’re tackling complex particle interactions or optimising your designs, the aim of this article is to equip you with the tools to elevate your projects and drive innovation.

Rocky DEM for Transfer Chutes, Conveyors and Bulk Materials Handling

LEAP recently ran a webinar that explored how Rocky DEM is helping engineers and equipment designers around Australia to easily troubleshoot existing issues and optimise their designs to avoid chute blockages due to wet/cohesive materials, improve longevity of wear liners and better configure chute flow to reduce belt misalignment and tracking issues.

This article summarises this presentation and includes video highlights including demonstrations of how Rocky DEM simulations help designers assess the overall performance of bulk materials handling systems.

Rocky DEM for Heavy Equipment Design

For engineers working in heavy equipment design, the ability to analyse and predict the behaviours and responses of structures in varying operating conditions is critical to ensure both safety and optimal equipment performance. At LEAP, our decades of experience with DEM has put us in the perfect position to help our customers to implement Ansys Rocky DEM, coupled with Multi-Body Dynamics (MBD) and Finite Element Analysis (FEA) solvers. This article explores the various ways that Ansys Rocky can be combined with other tools within the Ansys product portfolio, to deliver higher fidelity simulations – with a focus on the heavy equipment industry.

Honouring the legacy of pioneering Chemical Engineering researcher, Emeritus Prof. Owen Potter with the help of simulation

Invented by Emeritus Professor Owen Potter AM, a globally renowned chemical engineer, the Venso Flow fluidisation process has significant potential to improve the efficiency and sustainability of many industrial processes. Driven by honouring her father’s legacy, learn how Caecilia Potter and her VensoGrow team are using insights from simulation and IoT control systems to help further improve the process and apply it to seed coating applications.

Finding the sweet spot with GPU vs CPU hardware for faster processing in Rocky DEM

Engineers running particle simulations now not only demand faster solution times but also want to increase the fidelity of their DEM simulations using millions more particles. Fortunately, advances in GPU capabilities have meant that Rocky DEM customers can take advantage dedicated GPU-based solvers – but what is the hardware sweet spot for different problem sizes? Here we review a comprehensive set of benchmarks completed by the Rocky DEM developers comparing solve times on CPUs vs GPUs.
