Ansys Rocky is the industry-leading discrete element method (DEM) software used for simulating the motion of granular and discontinuous material.
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.
Using DEM to design a more robust heat exchanger
Compared to bench-top component-level testing, overall foulant simulation can produce savings of up to 10% of total development costs — along with reduced time to market, since results are available in a week, compared to months.
Built-in appliances fill today’s high-end kitchens, in which seamless integration with cabinetry can pose technical challenges related to airflow restriction in a machine’s compartment. This problem is exacerbated by dirt accumulation on the condenser (heat exchanger), which can affect appliance performance.
Experimental evaluation of dirt accumulation on condensers is time-consuming and expensive. Consequently, Sub-Zero is coupling Ansys Fluent computational fluid dynamics (CFD) and Ansys Rocky discrete element modeling (DEM) to quickly gain insight on the mechanisms behind dirt accumulation in an effort to design a more robust heat exchanger.
January 2024
In 2024 R1, Ansys Rocky continues to address customers' needs, delivering features that enable users to perform DEM (Discrete Element Method) simulations, keeping the focus on multiphysics, providing new SPH (Smoothed Particle Hydrodynamic) capabilities, and optimizing user experience, allowing limitless possibilities on particle dynamics simulation.
Perform DEM simulations leveraging new enhancements, including thermal coupling with Ansys Mechanical, particle transparency analysis, and liquid bridge compatibility with course graining.
Enhanced SPH capabilities enable faster simulation by gaining performance with the new incompressible SPH (iSPH) algorithm, new viscosity models for non-Newtonian fluids simulation, SPH 1-way coupling with Ansys Fluent and Heat Transfer Coefficient (HTC) without requiring a thermal solution.
Automation and flexibility with PyRocky, a new user interface with style standardization and the dark theme, Rocky documentation under Ansys Help, and AIS Rocky are one place for self-learning and community interaction.
