Granuleworks’ intuitive user interface can handle an entire simulation, from pre-processing through post-processing. You don’t have to be an expert to edit simulation parameters or keep track of multiple projects.
The 3D view window features ultra-fast, high quality OpenGL rendering optimized for large-scale simulation with millions of particles. The window system is highly customizable, letting you compare multiple result side by side. Both Windows and Linux are supported.
GPU/CPU High Performance Computing
Granuleworks is optimized for the latest CPU/GPU architectures. The latest version of Granuleworks 1.1 supports the NVIDIA Volta generation GPU platform CUDA9.1, the world's most powerful GPU architecture, developed as a computing engine for computational science and data science. This provides an additional performance boost to Granuleworks' calculation speed.
Granuleworks can be used to evaluate the amount of powder transport, improve the transportation device, and optimize the transport conditions, as it enables to accurately reproduce the repose angle, bulk density, etc., by using the rotational resistance model. In addition, application to vibration transfer is also possible by forcing the device to move.
A technique that reduces the number of particles and improves calculation speeds by replacing multiple original particles in a granular system by large particles (coarse-grained particles) is called coarse-graining technology. SDEM (Scalable DEM), which is one of the course-graining technologies, is implemented in Granuleworks. By using SDEM, bulk density can be considered in scale particles and setting parameters at one scale, will give similar behavior at other scales. It demonstrates power in DEM simulation of actual machines, as it supports particle size distribution, as well as rolling resistance model and van der Waals force.
Coupled Simulation with Particleworks
Powder and liquid flow
Prometech’s Granuleworks enables you to simulate complex phenomena such as mixing and stirring, in addition to mechanical conveying possesses. By combining Granuleworks’ DEM (Discrete Element Method) and Particleworks’ MPS (Moving Particle Simulation), you can simulate the motion of powder particles in fluids.
Coupled Simulation with RecurDyn
Motion and powder coupling
By combining Granuleworks with RecurDyn, a Multi Body Dynamics Simulation software of FunctionBay, Inc., it is possible to simulate the powder behavior in consideration of the motion of the mechanism according to reality. Sending the mechanical model behavior (position and velocity information) calculated by RecurDyn to Granuleworks, and returning the powder simulation results (powder force) from Granuleworks back to RecurDyn, realizes a bidirectional coupling analysis of both motion and powder.
Visualization Option [Optional Product]
Visualization Option is an optional program that converts the simulation results of Particleworks and Granuleworks into a general-purpose CG format and enables CG editing and rendering using CG software. It streamlines visualization from CAE simulation results and accelerates video creation and XR (VR / AR / MR) content development.
Converting Simulation Results to CG Formats Compatible with Various Software
Using Visualization Option, you can import simulation results to Digital Content Creation tools such as Maya, 3ds Max, Blender, as well as game engines like Unity, Unreal Engine, and so on. The data size can be optimized using the function to reduce particle/surface polygons.
Photoreal Visualization Made Easy for Analysts
Visualization Option Version1.0 comes with a program (Visualization Option for Unity) that enables video rendering and content output easily from Unity. It automatically imports simulation results and sets up the scene environment, timelines, cameras, and lights. You can set the textures by merely selecting from the basic material library equipped with Visualization Option. Even if you are not familiar with CG software or content editing, you can create photorealistic rendering and video output with ease using Visualization Option for Unity.
Creating XR Content Directly from Simulation Results
You can create XR (VR / AR / MR) contents by loading simulation results into Unity or Unreal Engine. Some of the latest CG technologies such as physically-based rendering that precisely expresses realistic textures and NVIDIA RTX (real-time ray tracing) that enables accurate reflection and refraction are available for visualizing simulation results.
