ANSYS Rocky 2021R2 version 21.2.0

ESSS partners with Ansys to unveil new ANSYS Rocky 2021R2 (version 21.2.0) is the industry-leading discrete element method (DEM) software used for simulating the motion of granular and discontinuous material.

What's New - Date: July 2021


Large Particle Simulation Speed-Ups
Includes improvements in speed and stability of applications requiring two-way Ansys Rocky and Ansys Fluent coupling, especially for models involving large particles.


API Enhancements
Enhancements in Rocky’s customization API add flexibility for heat transfer, breakage modeling, geometry wear and more.


New Ansys Motion Coupling
New connection with Ansys Motion more tightly integrates particle dynamics with multibody dynamics where rigid and flexible motions are important.


Rocky is designed to solve engineering problems. Rocky is uniquely capable to models real particle shapes including any solids, 2D shells, and rigid and flexible fibers. The simulations are fast and accurate. With multi-graphics processing unit (GPU) solver technology, you can simulate the behavior of different shaped and sized particles in many industrial applications.

ESSS and Ansys are working to improve Discrete Element Modelling (DEM) workflows for quickly analysing and assessing particle movement.

Interoperable with Ansys’ flagship solvers (Fluent and Mechanical), the new workflow, called Ansys Rocky, helps engineers ‘design highly reliable products, slash development time and win the race to market’.

According to Ansys, nearly 70 per cent of industrial products experience bulk granular material flows, where different-sized particles with complex shapes interact, potentially impacting a product’s efficiency or structural integrity.

To overcome this difficult design challenge, engineers require DEM, coupled with structural and fluid analysis, to assess the flow behaviour of these granular particles early in the design phase.

The new workflow is a robust 3D DEM solution for tackling particle movement design issues. It uses the multiple GPUs simultaneously to analyse bulk material flow systems 20-90x faster, Ansys Rocky runs high-fidelity, uncompromised massive particle models.

It is integrated with Ansys Fluent and Ansys Mechanical and swiftly simulates fully coupled fluid and structural systems’ bulk material movement and reaction to forces such as gravity and adhesion, ensuring new products are more reliable than ever.

Ansys claim that unlike a traditional DEM code, Ansys Rocky accurately models particles shapes including arbitrary 3D shapes, 2D shells and flexible fibre, helping engineers quickly solve challenging design problems with very complex geometric design variations.
