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

Abstract

Modeling & Simulation (M&S) is a technology that replaces the physical productionand experimentation of products with virtual production (modeling) and engineeringanalysis (simulation). M&S can greatly reduce the time and cost it takes to develop newproducts and thus increasing the manufacturing company's competitiveness. This paperdescribes the construction of M&S platform based on High Performance Computer(HPC) cloud. High performance Engineering MOdeling & Simulation (HEMOS) is aM&S software developed to support structural analysis and fluid analysis. Developedusing open-source software, it supports all M&S processes from pre-processing toanalysis and post-processing. HEMOS is developed to simplify shapes, create mesh, anddetect contact surfaces at the pre-processing. It uses CalculiX and OpenFOAM, bothopen-source solvers, to analysis structural and fluid problems without license restrictionsat 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 with532 CPU cores and is connected with KISTI’s supercomputer of about 300TF. This HPCCloud-based modeling and simulation platform that services HEMOS can increase useraccessibility and reduce costs.
