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.

Integration of Rocky DEM + Ansys for Particle-Fluids systems

Rocky is a powerful, 3D DEM program that quickly and accurately simulates particle behaviour within bulk materials handling systems used across a variety of industries including mining and minerals processing, food and beverage, pharmaceutical, agricultural and any industry dealing with particulate systems or solids handling applications. Some keys features include: an extensive library of realistic...

Predicting Liner Wear in a SAG Mill using Rocky DEM coupled with ANSYS CFD

LEAP will be in Melbourne at the 2nd Int'l Symposium on Computational Particle Technology to showcase exciting new modelling work that has been completed recently using Rocky DEM and ANSYS CFD to predict liner wear in a semi-autonomous grinding (SAG) mill, using ANSYS CFD to model the effects of slurry flow within the mill on liner wear and particle breakage.

Using CFD to enhance your mixing process and drive down costs

Mixing processes are critical to a wide range of industrial applications across the the paint, food, pharmaceutical, minerals and water treatment industries. CFD is becoming fundamental to the successful operation of mixing processes including clarification, cell culture growth, fermentation, polymerization and blending.

Tips & Tricks: How to interpret results for multiphase & porous domains using true velocity and superficial velocity

A commonly asked question is: What is Superficial Velocity and when do I use it?   If a fluid flows through a region that is occupied by either fixed structures (a porous region, pipe rack, catalyst bed, etc...),¬†or shares the channel with other fluids (e.g. gas-liquid flow), there are two ways to describe the fluid...
