A scientific workflow service with intuitive Problem Solving Environment for Aerodynamics

Abstract

Designing a scientific workflow for a complicated scientific application is now a trend to make the management of the problem simple and reuse the experiment for other simulations. Scientific workflow automates a repetitive cycle of transferring data and performing complex operations in a straightforward way in order to make it easier for scientists. Therefore, scientists could focus on their research regardless of paying concern about management of computing. In this paper, we propose a scientific workflow service for multi-stage aerodynamic application in PSE (Problem Solving Environment). This workflow service in PSE provides an integrated workflow construction facility to map an experiment flow with designing, execution, monitoring and visualization services within an environment. Furthermore the service enables a user to interactively control over scientific simulations while the computations are in progress. With the presented high-level front-end, scientists easily modify a flow of their experiment and extend their work with pre-existed work modules without risk of design errors. As a proof-of-concept, we target a science portal for solving a CFD (Computational Fluid Dynamics) application in Aerodynamics study and show the implementation of this proposed scientific workflow service in the portal. © 2012 GIRI.
