Prometech Software, Inc. (President: Tsuyoshi Sumiya, Head Office: Tokyo, hereinafter Prometech) today released the English version of “Visualization Option”, an optional product for Particleworks and Granuleworks.
 
Visualization Option is a tool for engineers and CAE analysts to easily perform photoreal visualization from simulation results obtained by Particleworks (liquid-flow simulation software) and Granuleworks (granular material simulation software). This optional product enables CG production by converting simulation results to CG formats compatible with various software. Visualization Option realizes high quality and diverse visualization expressions that are effective in digital reviews (presentations, sensory evaluations, etc.) and marketing and sales materials. Prometech plans to further develop this product to help engineers and CAE analysts to easily create 3DCG movies.

Since its establishment in 2004, Prometech has been providing software and services aiming to merge simulation technologies and CG technologies. Along with the sales and technical support of CAE software, Prometech offers state-of-the-art visualization services using the latest computer graphics technology. Such services include creations of special graphical content, photoreal and high-quality CG video content, and interactive XR (VR/AR/MR) content, all of which are created by using simulation results, CAD data, drawings, and photos.
 
Having transferred “DWANGO CG Research”, a computer graphics research institute, to Prometech, we have successfully established “Prometech CG Research” as one of our divisions in early 2019. We are continuously investing in computer graphics research and development. We believe that the release of Visualization Option will accelerate the fusion of simulation and CG and lead to innovative technologies in product design, development, and evaluation in a wide range of industries.

Prometech Software, Inc. (President: Tsuyoshi Sumiya, Head Office: Tokyo, hereinafter Prometech) released “Particleworks for ANSYS 1.2”, an enhanced version of the interface product between Particleworks and the world-leading multiphysics simulation software Ansys, on July 1, 2020.

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, electronic, 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. There have been many inquiries related to complex physical phenomena through the coupled analysis of Particleworks and other CAE software, and it is expected that its utilization will spread further.

Particleworks for ANSYS is an interface product for Ansys that complements the wide analysis area of Ansys and further expands the range of phenomena to be studied. This product allows you to use Particleworks on the Ansys Workbench environment. Combined with the simulation functions of Ansys, it enables coupled calculation with Ansys Mechanical such as structural deformation calculation and thermal calculation using the fluid pressure and heat transfer coefficient obtained by Particleworks. You can also use the airflow obtained by Ansys Fluent (CFD software), apply it to Particleworks, and run coupled calculation. The latest version of this product, Particleworks for ANSYS 1.2, supports the airflow obtained by transient calculation in addition to the airflow from steady-state calculation in Ansys Fluent.

Here is a jet spray example. 

1. Start with Ansys Fluent to run the airflow simulation around a jet spray
2. Run Particleworks to analyze the behavior of the sprayed water based on the transient airflow data obtained by Ansys Fluent.

You can accurately capture the movement of the sprayed water that changes over time with such coupled calculation. These operations are done on Ansys workbench with Particleworks for ANSYS 1.2 in an easy manner.

The combination of Ansys Fluent and Particleworks in the Ansys Workbench environment now supports transient calculation. Prometech believes that the evaluation and understanding of fluid phenomena in the design and development phases will further accelerate with Particleworks for ANSYS 1.2 and that it will contribute to strengthening the competitiveness of its users. We will continue expanding and enhancing the functions of the interface between Particleworks and Ansys.

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.
