Fluid flow simulation is one of the most important tools for engineers and mathematicians in the development and improvement of products in a wide variety of industries. Fluids can be liquid or gaseous and flow through or around an object. Simulation is used to predict the behavior of fluid flows on and in complex structural parts. This allows the effects of flowing fluids to be analyzed during the design phase, problems to be detected at an early stage and the performance of the product to be optimized. Due to the increasing capacity of computing power and the continuous development of models and algorithms, Computational Fluid Dynamics (CFD) has become an essential component in the simulation of flow behaviour.
Scientists, engineers and designers can achieve significant savings in experimental analysis through the use of appropriate software, as they no longer need to build physical prototypes. This enables faster and more efficient development of new approaches and shortens the innovation cycle of new products. One field of application of flow simulation is, for example, the calculation of the aerodynamics of car bodies.
AIM
The goal of HoloSim is to enable engineers to analyze simulation data using mixed reality by embedding holograms as 3D models in the working environment and making them interactively accessible. HoloSim connects experts all over the world and allows Mixed Reality Meetings with an individual or synchronized projection of the simulation data, enabling an innovative way of collaboration. The particular challenges in the project are the holographic representations of highly detailed CAD models and the seamless integration of the application into the end user’s existing workflow. For this purpose, automated methods are developed and neural networks are used for polygon reduction. Further challenges are the particularly precise visualization of the simulation data as well as the design of the application for the collaborative work of several users at different locations.
The solution addresses all industries that use fluid flow analysis to develop and design parts. Examples include the entire automotive industry, the aerospace industry, the construction industry, in the design of industrial plants or as support for users in the service sector. If you look at the automotive industry alone, the aerodynamics of automotive components is a particularly important and challenging subject area, in which a great deal of effort is invested, especially with regard to optimizing fuel consumption and maximizing the range of electric vehicles.
PROJECT CONSORTIUM
The HoloSim project consortium consists of hololux GmbH, the AWS-Institute, Create-3D and M.TEC Engineering. MANN+HUMMEL GmbH is also integrated into the project as an associated partner. In HoloSim, the AWS-Institute plays the role of the research partner and deals with research-intensive topics in the project. Thanks to its technical expertise in the fields of VR/AR/MR, Computer Vision and Deep Learning, new approaches for the transformation and optimization of CFD simulations for display on VR/AR/MR devices are to be found.
In particular for collaborative cooperations in virtual worlds, the institute deals with the research question of how the working worlds of the future can be designed and is working in the project on the concrete implementation of the software for native application on MR glasses for the joint analysis of CFD simulations in mixed reality.
