Prometech has released the particle-based simulation software “Particleworks Ver. 8.0.0” and the granular materials simulation software “Granuleworks Ver.3.0.0”.

Prometech Software, Inc. (CEO: Toshimitsu Fujisawa, Head Office: Tokyo, hereinafter Prometech) has released the particle-based simulation software “Particleworks Ver. 8.0.0” and the granular materials simulation software “Granuleworks Ver.3.0.0”.

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.

【 New capabilities of Particleworks 】

■Multi-resolution
This method divides the simulation domain into the Coarse domain and the Fine domain, which are computed using coarse and fine particles, respectively. By only placing fine particles in areas that require high resolution or are narrow, it is possible to reduce computational load and memory consumption.

■MPFI
MPFI is a method that simultaneously calculates the pressure and viscosity terms of the Navier-Stokes equations implicitly without separating them. This method is effective for problems with low Reynolds numbers and high pressure, such as the flow of high-viscosity fluids like resins.

■Snow model
We provide the modeling of snow as a Bingham fluid (a fluid that does not flow until it is subjected to a certain shear stress). This allows for calculations such as snow compaction behavior, where snow is deposited and compressed.
