Prometech Software, Inc. (President: Tsuyoshi Sumiya, Head Office: Tokyo, hereinafter Prometech) has released the particle-based simulation software “Particleworks Ver. 7.1” and the granular materials simulation software “Granuleworks Ver.2.1”.

Particleworks is a CFD simulation software based on MPS -moving particle simulation- method. By using particles as calculation points without mesh generation, it greatly reduces the number of pre-processing steps such as simulation model creation and simulates complicated liquid behaviors including large-scale deformation of free surfaces such as oil behavior of power train, piston oil cooling, vehicles driving into the flooded road, mixing of food, chemicals and resin, debris and concrete flow, and tsunami runup, etc. Because of such simulation capabilities, Particleworks has been attracting attention in various fields including automotive, machinery, electric, material, food, chemical, biomedical, energy, and civil engineering industries all over the world. 

Granuleworks is a granular material simulation software based on the discrete element method (DEM) theory. It can be used for manufacturing processes using powders, powder processing, and design and improvement of powder equipment for various fields including food, pharmaceuticals, chemicals, transport equipment, and electronic materials. Besides, by coupling with Particleworks, it can also simulate bubbles’ behavior in liquid.


【 Common new/enhanced capabilities of Particleworks and Granuleworks 】

Improvements in usability and performance
To improve usability and performance, a run-time post-processing function has been implemented that can run concurrently with the solver.
This allows post-processing to be performed even at finer time increments than before and reduces file size and processing time.

Free viewer
Free-viewer, a GUI for viewing analysis results without a license, has been implemented.


【 New capabilities of Particleworks 】

Zooming function
The zooming function, which allows you to fine-tune the particles in the analysis region you want to focus on, has been implemented as an official feature.

Multi-GPU performance improvement
With two GPUs, the speed is about twice as fast as before, and with four GPUs, the speed is about three times faster.

FVM: Calculation performance improvement and officially implemented
The airflow analysis function using FVM: Finite Volume Method, which was previously a beta function, is now an official function. By coupling this airflow analysis with liquid analysis using Particleworks' MPS, you can efficiently analyze gas-liquid two-phase flow. Also, the calculation time has been reduced to less than half of the previous beta version.
