Making the Most of CFD Analysis by Effective Coordination with BIM

The demand for solutions to energy problems continues to grow, which underlines the significance of reducing energy consumption in the context of architecture lifecycle. SHINRYO CORPORATION has made remarkable achievements in the field of air-conditioning system design, which is crucial for solving this energy issue. They have introduced a way to incorporate CFD into their BIM system. This has equipped their engineers with the design tools needed to optimize air-conditioning systems.

 Shinryo Corporation is a leading company in the design and installation of air-conditioning for building facilities. They have long provided district heating and cooling systems for entire cities, and the quality of their product is highly regarded. Shinryo Corporation’s objective is to realize mutual sustainability for both human lives and the environment by implementing advances in environmental engineering technology.

 Shinryo Corporation’s three decades of experience using 3D-CAD is one of the enablers that has helped the company consistently produce low cost and high quality services. They developed their own BIM compliant software, S-CAD, based on Syspro’s 3D-CAD software, DesignDraft, which is frequently used by architecture designers. S-CAD allows engineers to review models in 3D, simulate construction, run pipe interference checks, calculate static pressure and lifting height, and undertake quantity surveying. They are currently developing a 3D laser scanner that generates 3D models of existing facilities.

 Mr. Ken Fukada from Shinryo Corporation, a researcher in the CFD Solution Group under the R & D Center, explains that the company started to apply S-CAD ten years ago. Mr. Fukada himself has been working with CFD applications since he joined the company. Shinryo Corporation has created education programs for S-CAD, which is now at the center of their operations; new staff members attend on-site training for their first six months where they learn how to use S-CAD and the basics of facility design. The company also offers continuous training opportunities for staff members to improve their engineering skills and knowledge.

Customizing CFD to Streamline Tasks

 S-CAD was linked to Cradle’s CFD analysis tool, scSTREAM, to perform fluid analysis of air-conditioning systems. Shinryo Corporation undertakes more than 150 CFD analyses a year with 70% of them being performed by design engineers. The engineers use the analysis for initial design and also for construction and promotion of their products. Mr. Fukada reveals that improving energy efficiency has been one of their clients’ top concerns in recent years.

 Shinryo Corporation reports that scSTREAM is useful fluid-thermal software, as they have been applying it for more than two decades across their nationwide locations, concurrently providing the ideal computing environment and hardware for their engineers to effectively perform analysis. Despite their successes, the company has realized two growing concerns; first, design engineers have been given more tasks to do, and second the accuracy of analysis results can be more dependent on engineers’ skills and experience. To enhance efficiency and improve the quality of analysis, Shinryo Corporation revalidated their internal training program and also investigated ways to combine scSTREAM and S-CAD.

 In 2008, they established their CFD Promotion Center to provide more support for analysis tasks, followed by installation of an HPC server in their R & D Center in 2010. This enabled their engineers to carry out analysis from different bases by acquiring licenses through the network. Mr. Fukada’s division, the CFD Solution Group in the R&D Center, complements the efforts with their work writing new software and developing expertise tackling more complicated analyses.

 In pursuit of combining scSTREAM and S-CAD, the CFD Solution Group developed add-in software, S-Pre, which facilitates the transfer of data between S-CAD and scSTREAM. When working with design data for building facilities, S-Pre transfers only the data necessary for the CFD analysis from S-CAD to scSTREAM via Cradle’s VBI. Engineers can specify CFD settings easily using the customized tool box in the S-CAD window.

 The development of S-Pre started five years ago, when Mr. Fukada joined the company. Engineers had provided feedback that importing 3D-CAD data directly to scSTREAM would provide significant value. This led to the development of the add-in function to enable the model transfer. Previously, engineers had to re-model each time they conducted an analysis using scSTREAM. This created much additional work because the engineers had to extract all the design information from the original drawings. When the analysis and design functions were performed by different engineers, communication errors frequently occurred. In contrast, by using S-Pre, all engineers can directly use the data from S-CAD and avoid communication related errors. Even those who are unfamiliar with operating scSTREAM can set up analysis conditions from S-CAD.
