Press release – Ansys Acquires Leading Particle Dynamics Simulation Software Rocky

Ansys, the global leader and innovator of engineering simulation software, announced today the acquisition of Engineering Simulation and Scientific Software Rocky DEM, S.L. With this acquisition, Ansys adds Rocky, the leading discrete element method (DEM) tool, and a skilled team of developers, application support technicians and customer-facing staff in Brazil, Spain, and the United States. The transaction is not expected to have a material impact on Ansys’ consolidated financial statements in 2023.

Rocky was a subsidiary of Engineering Simulation and Scientific Software (ESSS), a long-term Ansys Channel Partner, and developer of engineering software dedicated to modeling discrete mechanics problems. Ansys’ acquisition of Rocky builds on the companies’ long-term partnership and joint particle modeling workflow announced in 2021. Rocky’s software, with specific strengths in GPU computing and applying particle methods to multiphysics simulations, is used in wide variety of cross-industry applications that involve discrete solids of any size and shape.

Particle modeling spans many industries and applications; particles can consist of medical tablets, food snacks, agriculture seeds, powders, and even fibers used in filtration devices. Industry leaders are challenged to improve their product quality and find solutions to help accelerate their decision-making related to the design, manufacturing, and operation of their particulate systems.

Rocky is a leading DEM software package that quickly and accurately simulates the dynamic flow behavior of discrete solids and particle-laden free-surface flows in multiple industries. Rocky simulations provide powerful insight to help reduce waste, improve product quality, increase product uniformity, predict performance and durability of equipment during operation, meet resource management, and address sustainability concerns.
