HEMOS-Cloud: HPC Cloud-based Modeling and Simulation Platform for HEMOS Software

Abstract

Modeling & Simulation (M&S) is a technology that replaces the physical production and experimentation of products with virtual production (modeling) and engineering analysis (simulation). M&S can greatly reduce the time and cost it takes to develop new products and thus increasing the manufacturing company's competitiveness. This paper describes the construction of M&S platform based on High Performance Computer (HPC) cloud. High performance Engineering MOdeling & Simulation (HEMOS) is a M&S software developed to support structural analysis and fluid analysis. Developed using open-source software, it supports all M&S processes from pre-processing to analysis and post-processing. HEMOS is developed to simplify shapes, create mesh, and detect contact surfaces at the pre-processing. It uses CalculiX and OpenFOAM, both open-source solvers, to analysis structural and fluid problems without license restrictions at the analysis while OpenGL and Paraview were used to implement post-processing. HEMOS is provided through HEMOS-Cloud which was built based on Xen server with 532 CPU cores and is connected with KISTI ’ s supercomputer of about 300TF. This HPC Cloud-based modeling and simulation platform that services HEMOS can increase user accessibility and reduce costs.
