본 연구에서는 이종 그래픽 저작 도구를 이용한 SMFD 화면 시현 소프트웨어 작성을 목표로 한다. 그래픽 저작 도구는 화면에 시현할 그래픽 요소의 위치, 움직임 등을 보다 손쉽게 사용자 친화적으로 설계 가능한 방안을 제공하고, 설계 내용을 소스 코드로 변환하며, 해당 소스 코드로 생성한 소프트웨어를 대상 시스템에서 구동하기 위한 그래픽 엔진을 제공한다. 이에 따라 그래픽 엔진은 그래픽 저작 도구 및 적용 대상 시스템에 의존적이다. 특히, 단일 시스템에서 이종 그래픽 저작 도구를 통해 개발한 소프트웨어 구동 시 다수의 그래픽 엔진 운용되며, 이는 여러 문제를 초래할 수 있다. 본 논문에서는 이종 그래픽 저작 도구를 사용한 SMFD 화면 시현 소프트웨어 개발 과정에서 발생한 문제와 이에 대한 해결 방안을 기술하였다.

A submarine good military weapon because of its confidentiality and intimidating power. Therefore, training warfighters how to maneuver submarine is very important. Because submarine is very expensive and has regional and temporal limitations, M&S(Modeling and Simulation) can be a good alternative. However, as the existing M&S systems of submarine generally use expensive commercial software and dedicated hardware, which cause the warfighters to take troubles to visit the secured places, and then to train themselves during limited time slots. Also, many M&S systems have only one-channel display system which reduces the sense of immersiveness. Another problem is that many heterogeneous simulators can hardly be used as an integrated system. To solve these problems, X3D, a platform-independent and open standard graphic file format, is used with the general-purpose PCs. To increase immersiveness, multi-channel display system and a motion chair are used. Finally, HLA/RTI is used to integrate individual components of the simulator. All of these are verified through experiments.

Structure and/or fluid analysis is gradually increased by an essential design process in the small and medium-sized businesses (SMBs) because of the needs for a rapid design process and the certification about the supplement of the parts by the large business (LB). In this paper, we developed the web-based ezSIM platform installed in the resources integrated system server. The ezSIM platform is based on the heterogeneous linux and windows operating system for the user-friendly connection with the part of the analysis for the SMBs. The procedure of the structure/fluid analysis service module using the public software and the license-free open code in the ezSIM platform was explained. The convenience of the ezSIM platform service was presented by the reaction rate of the graphic motion compared with that of a local PC and the solving and pre-post processing interface compared with that of the KISTI supercomputer. The web-based ezSIM platform service was identified as a useful and essential platform to the SMBs for the usage of the structure and/or fluid analysis procedure.
