Development of cloud software services for computational analysis of blood flows

Abstract

This paper presents the development of the cloud software services for computational analysis of blood flows on a private university cloud. The main focus is on the software service level built on the top of the computational platform provided. Moreover, user friendly management tools have been developed by using the Apache jclouds API to enhance the management of OpenStack cloud infrastructure and to increase the accessibility of engineering software. The blood flow through an aortic valve is considered as a pilot application of the private cloud infrastructure. The investigated flows can be described using numerical models based on viscous incompressible Navier-S tokes equations. The modelling software environment based on ANSYS Fluent is developed as a software service (SaaS) for the numerical analysis of low flow, low pressure gradient aortic stenosis. The performance of the developed cloud infrastructure has been assessed testing CPU, memory IO, disk IO, network and the developed software service for computations of blood flow through an aortic valve. The results obtained have been compared with the performance obtained using the native hardware.
