Prometech has released “Particleworks for ANSYS”, an interface product for world leading Multiphysics CAE “ANSYS”
Prometech Software, Inc. (President: Tsuyoshi Sumiya, Head Office: Tokyo, hereinafter Prometech) has released Particleworks for ANSYS, an interface product between Particleworks and the world leading multiphysics simulation software ANSYS on July 25th.
Particleworks, a liquid-flow simulation software based on the moving particle simulation (MPS) method, has been introduced in many industrial fields because of its mesh-free, easy-to-use operation and unique simulation capabilities required for fluid phenomena such as liquid drop, mixing, lubrication, spraying, sloshing and splashing. Its appeal to a broad range of users not only in the automotive industry, but also in the machinery, electric, material, food, chemical, biomedical, energy, and civil engineering industries all over the world has been growing over the past 10 years since its first release in 2009.
Today, demand for such complicated liquid flow simulation is increasing not only in niche users but also a growing number of CAE engineers that work with structural, dynamic, thermal, electromagnetic, and/or general fluid flow analysis, who expend considerable effort to determine the influence of liquid flows to and from those physical behaviors. This is also true for users of ANSYS, the world-leading multiphysics simulation software.
Particleworks for ANSYS is developed to provide a specialized, fast simulation tool for customer’s performing liquid flow simulations with large free-surface deformation, complementing Fluent’s high-resolution, high-accuracy free surface results. Particleworks is now integrated into the ANSYS Workbench environment and can be combined with ANSYS’ simulation capabilities for more realistic product design evaluations.
Incorporating Particleworks into the ANSYS Workbench environment enables key features, such as calculating the deformation of a structure caused by fluid pressure, and the transfer of heat from a structure with the heat transfer coefficient. Fig. 1 shows the launch menu of Particleworks in ANSYS Workbench and Fig.2 shows the simulation flow from the liquid flow simulation in Particleworks to the heat transfer simulation in ANSYS.
Particleworks can also be integrated with ANSYS Mechanical for calculating e-drives and the cooling of internal combustion engines. In this case, the information about heat transfer and cooling from the Particleworks simulation can be automatically and seamlessly transferred to ANSYS Mechanical to take into account the efficiency of the oil cooling. ANSYS Mechanical will use the boundary conditions from Particleworks to accurately predict the temperature and stress of the e-drive or piston.
In addition, Particleworks can transfer the mechanical pressure distributions during a transient process, such as the pressure produced by the sloshing of fuel or any other liquid in a tank, or the forces produced by water, mud or snow on the bumper of car, to ANSYS Mechanical. In this case, the force history or time-dependent pressure distribution on the structure is mapped from the Particleworks’ CFD simulation to the mechanical analysis to design and verify the structural resistance under dynamic loads.
Starting Monday, July 1, the Prometech Software Osaka Branch will be relocated to the address stated below.
Thank you for your continuous support.

Prometech Software, Inc. (President: Toshimitsu Fujisawa, Head Office: Tokyo, hereinafter Prometech) has joined the SOLIDWORKS Partner Program.
Particleworks has long been established as a leading CFD software in use by companies to enable design engineers to easily and effectively perform trial & error design studies. Particleworks for SOLIDWORKS is a frontloading CFD Software that allows the user to perform all operations from within the SOLIDWORKS environment. It includes functions needed for fluid phenomena that are highly demanded at design sites but that are difficult to reproduce with conventional grid methods (e.g. splashing, mixing and spraying).
Prometech released Particleworks for SOLIDWORKS in Jan 2019. This is a newly developed entry version of the fluid simulation software Particleworks as an add-in tool for SOLIDWORKS®, based on Prometech's particle method (Moving Particle Simulation).
“By becoming accredited as a SOLIDWORKS® Partner Program, we will strengthen our collaboration with partner companies and continuously provide customers with higher quality functions and services.” Says Prometech President Toshimitsu Fujisawa.
Particleworks for SOLIDWORKS user’s voice:
Nobuhiro Yuhashi, Ph.D., Research & Development Dep., Research & Development Sec., Maruyama Mfg. Co., Inc.
Our company uses SOLIDWORKS as a designing tool. The engineers that mainly work on designs also use SOLIDWORKS Simulation to perform structural analyses. We believe it be very valuable for the CAD-tool to be an all-in-one environment from the model designing stage to the simulation post-processing.
We have been using other CAE software for fluid simulation purposes. However, conventional mesh-based methods are not very efficient for the calculation of complex fluid flow and free-surface flow such as liquid surfaces and sprays. We considered implementing Particleworks for SOLIDWORKS because of its meshfree method and its calculation effectiveness when it comes to free surface flows and large deformations. Further, we regarded its user-friendliness as valuable, because we intend to have both experienced and beginning designers to use CFD for design studies and as a verification tool in the future.
Conclusively, we were very pleased with Particleworks for SOLIDWORKS because of how easily unexperienced designers could operate it. It also was very appealing to us because of it being add-in Simulation Software for the SOLIDWORKS CAD-tool. Performing parameter studies was nearly effortless thanks to the ability to perform analyses directly from the designed 3D data. Furthermore, being able to observe the simulation and the CAD data on the same screen and at the same time, allowed us to continuously reflect on and improve our product design.
Designers are most familiar with their CAD environment. They did not feel any discomfort when using Particleworks for SOLIDWORKS thanks to its full integration in the CAD environment. Therefore we found it suitable to implement at our design site.
We hope to see new simulation capabilities including coupled field analysis with other CAE software tools, e.g. liquid flow and structural coupling, in terms of being add-in software for SOLIDWORKS.
Thank you for your continued support.

New Release- Meshless liquid flow simulation software “Particleworks Ver.6.2” - - Granular Materials simulation software “Granuleworks Ver.1.1” -
Prometech Software, Inc. (CEO: Toshimitsu Fujisawa, HQ: Tokyo. Hereafter Prometech) proudly announces that Particleworks version 6.2, the meshless liquid fluid simulation software based on the Moving Particle Simulation (MPS) method, and Granuleworks version 1.1, the granular simulation software based on the Discrete Element Method (DEM) is released on January 18, 2019.
Particleworks is a liquid flow simulation software based on MPS (Moving Particle Simulation), one of the particle methods. This innovative meshless calculation method where fluids are shown as a gathering of particles allows for stable and highly-accurate analysis of free surface flow. Particleworks is very effective when it comes to simulations of oil behavior in powertrains, engine oil cooling, splashing of water around the vehicle, mixing of chemicals and resin.

■ Particleworks & Granuleworks Shared Updated Features
Coupling with elastic bodies of the Multi Body Dynamics Simulation Software RecurDyn
Particleworks6.2 and Granuleworks1.1 enable to perform simulations using RecurDyn bidirectional coupled analysis with elastic bodies as well as rigid bodies. Large deformation calculations using R-Flex (linear elastic bodies) and F-Flex (nonlinear elastic bodies) can be reflected in real-time to polygon wall in Particleworks and Granuleworks. Simultaneously, RecurDyn calculates elastic deformation, dynamic stress and strain under fluid force calculated by Particleworks and Granuleworks.
Mixing Degree Evaluation
Powder and granular materials are segregated due to various characteristics, such as their particle size, their surface roughness and their particle shapes. There have been many studies based on statistics of mixed state analyses. However, due to statistical errors, it was impossible to correspond to local mixed states or to the mixed states of micro-components. Particleworks and Granuleworks solve this problem by using an evaluation system for mixing degrees based on entropy. Analyzing the degree of mixing according to arbitrary spatial resolution becomes possible because this method does not include statistical errors. This results in the wide potential of applications besides mixing equipment.
NVIDIA CUDA9.1 Support
Each Particleworks and Granuleworks version update renews the solvers and are optimized for the latest CPU & GPU architecture.
The latest Particleworks 6.2 and Granuleworks 1.1 support NVIDIA’s Volta generation’s CUDA9.1 GPU platform. Volta is today’s most powerful GPU architecture developed as a computing engine for computational science and data science. This significantly boosts Particleworks & Granuleworks analysis performance and allows users to perform large-scale simulations of up to tens of millions of particles.
■ Granuleworks: New Features
SDEM (Scalable DEM) is a new coarse graining technology for the discrete element method developed by Prometech. It is commonly known that stress networks are constructed within granular materials. This new technology is a theoretical construction based on the stress networks’ characteristics. This technology can be applied to the Gravital Control System (the system where the contact between the particles is most dominant), and makes difficult high coarse DEM-based simulations possible.
