Original technology research on computational design
Localizing customized computational design SW for Korea
Director Soonhong Han of KAIST Computational Design Center 

Advanced technology for education, research and industry
Optimum design for machines and parts requires knowledge in performance, materials, processing and cost. KAIST Computational Design Center in this respect aims to develop fusion contents specialized for optimum computational design and framework through securing original technology and industry-academic cooperation. Director Han says “The technology can create high added value with low unit price. As high tech manufacturing has become a global trend, Korea must need this technology to promote both national and global competitiveness.” Most design software used in industrial settings are foreign made. And we had to pay expensive royalty and limited access to use them for education, industry and research. For this, the center is working on localizing design softwares based on open sources, developing functions needed for industry and building a system to give prompt response to the users as well as providing training opportunities for students. The center’s research is divided into three parts. Firstly, it is ‘Development of Product Design System’ by using open source CAD. Characteristic forming-based model is applied to the system and exchanges of parametric model with computing thermal fluid and structural dynamics softwares are also used. In addition, ‘Topology’ and ‘Geometry’ methods are applied to solve the ‘Persistent naming’ problem of the existing systems. Secondly, it is ‘Development of Computation Engineering Design Programme’ for optimum multidisciplinary designs. For this, the center is pushing forward development of global level optimum structural design algorithm and is currently working with EDISON specialized center for various design education. The center also uses ‘Human interactive’ to improve analysis and convenience of design. Lastly, it is ‘Development of User Interface’ specialized for computational design and interactive products that can communicate with human beings. Realizing creative control interface through visualizing mapping and controling IoT and solving design tools of fragmentization of interaction design workflow are the core elements of the research. This is expected to be the foundation for building computational design framework based on organic integration of digital models and real models. 

Making it to be global
The center developed 14 kinds of computational design programmes based on analysis on current technologies and preliminary survey in 2014. The center also developed 19 computational design contents and 4 interface scenarios with other specialized centers to be used in universities and to foster manpower. In addition, the center held ‘The 1st Computational Design Competition’ last March and 53 of 25 teams from 8 universities participated in the competition. The center demonstrated its EdisonDesigner CAD System and Optimum Research on Evolutionary Algorithm. These two were published on the academic journal of CAD/CAM Society. Currently, the center is working on improvement of SW functions and development of additional programmes, educational resources and research materials. The center is also working with Computational Thermal Fluid Center and Structural Dynamics Center to improve related environment and to expand EDISON community and is planning to hold EDISON Contest in March 2016. Director Han says “Our design technology in machines, aviation, ocean engineering and industrial design still need much improvement due to lack of infrastructure and technological difference between academic world and industry. For this, I want to establish accurate evaluation index and competition system. Through this, we can foster talented manpower and promote industry-academic cooperation and national competitiveness.” Power Korea supports Director Han and KAIST Computational Design Center.
