In 2024 R1, Ansys Rocky<\/strong> continues to address customers’ needs delivering features that enable users to perform accurate DEM simulations keeping focus on Multiphysics<\/strong>, provide new SPH capabilities<\/strong> and optimize user experience, allowing limitless possibilities on particle dynamics simulation.<\/p>\n As usual, it also provides significant performance enhancements and usability improvements.<\/p>\n Take a look at some of the new functionalities:<\/p>\n This release brings a significant leap in equipment thermal analysis with the implementation of a 2-Way Thermal Coupling with Ansys Mechanical.<\/p>\n Users can now run thermal simulations in which particles and equipment affect each other in thermal solutions simultaneously, amplifying insights and boosting the depth of thermal analysis.<\/p>\n SPH Fluid Flow Simulation:<\/em><\/strong> In this simulation you can see the 2-way thermal coupling between SPH fluid flow inside the tubes, defined on Ansys Rocky (figures on the left), and a heat source applied to the geometry on Ansys Mechanical. Both are being computed through System Coupling and the heat transfer post processed with EnSight (figures on the right).<\/em><\/p>\n This feature is also very useful for DEM physics simulations.<\/em><\/p>\n The Coarse-Grained modeling compatibility was extended to cover the Liquid Bridge Adhesion model and the SPH-DEM Coupling, unlocking the ability to speed up more complex particle simulations.<\/p>\n Coating Simulation:<\/em><\/strong> With this type of simulation, you can estimate the coating distribution between the particles. In such case, Liquid Bridge plays an important role in the particle’s dynamics and can now be speeded up with Coarse-Grained model.<\/em><\/p>\n <\/p>\n Following the tradition, Rocky solver algorithms were improved to run even faster and larger simulations.<\/p>\n The figure above shows excellent performance gains of 40% for GPU Time and 25% for GPU Time Pace with 18 M elements, and 61% for GPU Time and 100% for GPU Time Pace with 9 M elements in a simulation with big geometries handling, compared to the previous version.<\/em><\/p>\n Several improvements were made to increase the post-processing and data analysis capabilities:<\/p>\n In plastic bags transport simulation, the shell particles that represent the plastic bags can be set to be transparent allowing for analysis of the contents within.<\/em><\/p>\n Everything that is good can get better, so in this new version we have worked to improve even more the Rocky’s Features that you already know, with the:<\/p>\n In the image above you can see a simulation with the 3D view duplicated.<\/em><\/p>\n Discover fresh perspectives in fluid simulation, leveraging the new state-of-the-art SPH capabilities for enhanced insights.<\/p>\n Cumulative wet time and tangential stress are critical analysis to be done to evaluate the dishwasher equipment design efficiency.<\/em><\/p>\n The evaluation of an electric motor’s cooling performance heavily relies on thermal simulations, where the analysis of the Heat Transfer Coefficient plays a crucial role.<\/em><\/p>\n The airflow resulting from gears movement significantly influences high-speed gearbox simulations and its influence on fluid flow can be represented by the SPH point cloud air drag module<\/em>.<\/em><\/p>\n The dynamics of fluids like ketchup require non-newtonian viscosity representation to be properly modeled and simulated.<\/em><\/p>\n <\/p>\n To deliver an even better experience when using Ansys Rocky, in this release we present you a new interface with:<\/p>\n The new Ansys Rocky dark theme stands as a modern and elegant choice, reflecting the current trend of refined and sophisticated design.<\/em><\/p>\n With PyRocky, developers and engineers are empowered to utilize Python’s capabilities effectively, enabling efficient pre-processing, post-processing, and data extraction from Rocky simulations. By leveraging Python client libraries, engineers can automate repetitive tasks, personalize workflows, and craft bespoke solutions tailored to their unique engineering needs.<\/p>\n *<\/em>PyRocky GitHub will be available on Feb 15th<\/sup> ,2024<\/strong><\/em><\/p>\nDEM | Multiphysics<\/h2>\n
