This enables users to directly couple EDEM to flexible body simulations to cover a wide range of applications such as belts, sheet panels, elastic membranes, and many more. This means geometry sections can change shape and deform with input via the EDEM coupling interface. The EDEM solver engines have been enhanced to facilitate continuous modification of a geometry structure during simulation. With EDEM 2019, API models can now be run directly on the GPU solver which means they can benefit from the performance boost that the GPU provides.īeing able to simulate how a geometry is being deformed because of a bulk material acting on it is something that is of key interest for numerous applications and which has been under development at EDEM. One of the key advantages of EDEM is the versatile EDEM API (Application Programming Interface) that enables users to write custom physics to model complex and advanced material behavior such as flexible fibers, sticky solids, and breakage.

The multi-GPU solver is fully double-precision to guarantee accuracy and has been developed on OpenCL thus providing flexibility for users to use either AMD or NVIDIA cards. In general, the larger the simulation (over 1 million particles), the greater the benefit from multi-GPU. Performance gains from adding a second GPU range between 30-90% depending on the distribution and size of the simulation. This means users can run large simulations faster, but it also opens more possibilities to run much larger simulations which would not be possible on CPU only.

Using multiple GPU processors increases the maximum size of simulation which can be run on GPU, as well as increasing performance. In parallel, innovative features and tools are being introduced including a Python library for easier post-processing of large amounts of data, the ability to simulate deformable geometries as well as a new breakage model.ĮDEM 2019 officially introduces the EDEM multi-GPU solver engine. EDEM, a market leader in Discrete Element Method (DEM) technology for bulk material simulation, announces the release of the latest version of its flagship software.Īs the demand for performing big simulations involving millions of particles of any shape and size increases, EDEM continues to harness the latest GPU technology to enable users to run larger and more advanced simulations faster.
