Rocky DEM and ANSYS coupling can ensure faster simulation and expand horizons

Rocky DEM continues to invest in Rocky and ANSYS coupling functionality and presents new highlights about the increased integration between these two tools

Strong integration between computer-aided engineering (CAE) programs is of great benefit for engineers because the different tools working together allow them to evaluate more aspects of the equipment and produce simulations that are much closer to real life.

Attentive to this market need, Rocky DEM continues to invest in ensuring tighter coupling between Rocky DEM and ANSYS tools and is now pleased to announce that Rocky DEM is fully integrated into the Workbench schematic.

This advancement provides engineers with the ability to perform coupled analysis of particle simulation together with other physics such as structural and fluids. For example, an engineer can feed any geometry from ANSYS Workbench into Rocky DEM, and Rocky DEM will then calculate and transfer back particle loads into the geometry from the DEM simulation.

Rocky DEM and ANSYS Fluent

This closer integration between Rocky DEM and ANSYS Fluent can be performed using both 1-way and 2-way approaches, depending upon the nature of the problem to be solved.

By using ANSYS Fluent, for example, this increased flexibility allows engineers to model granular-fluid systems, thereby enlarging the range of coupled particle-fluid processes that can be managed with numerical simulations.

Complex phenomena such as pneumatic conveying, granular drying, slurry flow inside grinding mills, or even chemical reactions between particles and fluids can be simulated and analyzed with the tighter coupling of these powerful tools.

Rocky DEM and ANSYS Mechanical

Another new capability is the integration of 1-way coupling with ANSYS Mechanical as a new system into the Workbench schematic. With this type of coupling, a Rocky DEM simulation having non-coincidental meshes calculates a particle load which is then passed to the Mechanical program to predict the structural response.

This method allows engineers to evaluate the tensions stresses and forces generated by granular matter as it interacts with materials handling equipment, such as transfer chutes and conveyor belts.

Including Rocky DEM into the Workbench schematic will also allow engineers to perform design optimization analysis, since Rocky input/output parameters are exposed to other ANSYS modules, such as DesignXplorer.

Other highlights of the new Rocky DEM release include a direct geometry link with SpaceClaim, true multiple physics simulation abilities, and pervasive parametric support for input/output variables, which generates benefits like output variables, design exploration, parameters correlation, surface response, and design optimization.

Rocky is a powerful, 3D discrete element modeling (DEM) program that quickly and accurately simulates particle behavior within a conveyor chute, mill, or other materials handling system. Rocky analyzes media flow patterns and energy absorption rates, particle breakage, and energy spectra analysis. The software optimizes life expectancy of conveyor belts and components, minimizes material spillage in a design, and reduces the need for dust control and suppression, among numerous other applications. This software is a revolutionary way to handle a problem through computer simulation.
