Beijing Xiliu Digital Technology Co., Ltd. was established in 2021, and its core team comes from Tsinghua University, Shanghai University of Science and Technology, Columbia University, and McMaster University, etc. The research team has been deeply engaged in fluid simulation, computer graphics, and artificial intelligence for more than ten years. Relying on the digital fluid simulation laboratory, noise elasticity laboratory, high performance computing laboratory, and flight control laboratory of the world's first-class universities, the domestic industrial software Aerocae was released in 2022 through the combination of industry, education and research.

The Aerocae system does not use any foreign software components or open source code, and from the algorithm principle to the hardware architecture, it adopts the new generation fluid simulation technology, which will bring comprehensive efficiency improvement and process optimization to the high-end manufacturing industry.

Product Introduction

Aerocae：

A NEXT GENERATION DOMESTIC HIGH-PERFORMANCE FLUID SIMULATION SYSTEM

Autonomous and controllable software systems

Aerocae system software was developed by the university team. Under the efforts of the three founders of Xiliu Digital, the company and the university laboratory actively carry out the transformation of scientific research results. Through the cooperation and verification with the automobile production enterprises, a set of domestic independent industrial fluid simulation system has been gradually established. Aerocae system does not adopt any foreign software components or open source code, and it is a product independently developed by Xiliu Digital with 100% independent intellectual property rights.  

Cutting edge intelligent product technology

Different from the traditional CFD software, the underlying solver of Aerocae is based on the new high-order and high-precision adaptive lattice Boltzmann model developed by the company, and is implemented by GPU highly parallel optimization, which can provide more efficient, stable, complex and high-precision transient flow simulation. At the same time, the pre-processing part of Aerocae realizes the automatic creation of multi-resolution grid points with arbitrary geometry and topology, which greatly simplifies the simulation process. Finally, the post-processing part of Aerocae supports various dynamic high-quality visualizations and graphics rendering, which further optimizes the presentation of simulation results. Combined with an integrated user interface system, Aerocae will provide more powerful support for product design based on fluid simulation.

A wide range of applications

Aerocae system supports multi-physics simulation, such as aerodynamic force, aeroacoustic, multiphase flow and thermal fluid, fluid-solid single and dual coupling in complex flow field, and can be used in automobiles, aircraft, high-speed trains and other transportation tools, as well as in the field of architecture, water conservancy, energy, etc. It can be used to predict the physical properties of wind resistance, lift, surface pressure and temperature field distribution, noise intensity and frequency distribution, so as to guide the design of related products.
