Prometech Software, Inc. (President: Tsuyoshi Sumiya, Head Office: Tokyo, hereinafter Prometech) has released Particleworks for ANSYS 1.1, an enhanced version of the interface product between Particleworks and the world-leading multiphysics simulation software ANSYS in December 2019.

Particleworks is a mesh-free liquid-flow simulation software based on the moving particle simulation (MPS) method, which is capable of complicated fluid simulations such as liquid dropping, mixing, lubrication, spraying, sloshing and splashing. Because of its easy-to-use operation and unique simulation capabilities, Particleworks has been introduced mainly in the automotive industry and other various fields including machinery, electric, material, food, chemical, biomedical, energy, and civil engineering industries all over the world. Coupling such complicated liquid behaviors with other physical phenomena such as structure, heat, and airflow, it enables more realistic design verifications much closer to actual products’ behavior. Consequently, high expectations for the easy-to-use interface between Particleworks and other CAE software products have increased recently.

Particleworks for ANSYS 1.0 released in July 2019, to respond to such demand. This interface product for ANSYS provides a specialized fast simulation tool for customers that perform liquid flow simulations with large free-surface deformation, complementing Fluent’s high-resolution, high-accuracy free surface results. It makes Particleworks to be able to be used in the ANSYS Workbench environment for combining with ANSYS’ simulation capabilities for more realistic product design evaluations. In version 1.0, coupling with structure has been added, which made structural deformation calculation by fluid pressure and thermal stress calculation using heat transfer coefficient possible. The newly released Particleworks for ANSYS 1.1 has been upgraded with the new capability of liquid simulations considering the effect of the airflow calculated by ANSYS Fluent (thermal fluid simulation software). 

Figs. 1 and 2 show the airflow simulation around the side mirrors using ANSYS Fluent and the simulation of raindrops behavior using Particleworks in consideration of the effect of the airflow respectively. In case airflow is not taken into account, raindrops move only by gravity, by which the streamline draws a parabola. When considering the airflow effect, physically realistic raindrops behavior caused both by gravity and the airflow around the side mirrors can be reproduced.

By realizing the coupling of ANSYS Fluent and Particleworks on the Workbench environment, it can be expected that evaluation and understanding of fluid dynamics behaviors in design and development processes will be promoted and it will enhance competitiveness in the future. Prometech will continue to expand its capabilities and release new versions of Particleworks for 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.

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. Its meshless technology and intuitive interface contributes to more effective product development and design optimization. In both Japan and around the world, Particleworks is implemented in a broad variety of industries including automotive, electronics, chemical, medical, food, and consumer goods. 

Granuleworks is a granule materials simulation software based on Distinct Element Method (DEM). Granuleworks is applied to a broad variety of powder processing and powder-based manufacturing processes, such as foods, medicines, chemicals, conveying equipment and electronics. It can be used for designing and improving powder equipment because of its straightforward analyses of powder phenomena such as mixing, conveying, filling and compaction.

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.

SDEM
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.
