Commercial Software for Low Pressure Industrial Applications Leveraging DOE Technology
- Spectral Sciences, Inc.
There is a critical need for accurate and efficient gas flow simulation methods for low pressure industrial chamber processes. SSI is leveraging the SPARTA library, developed by our partners at Sandia National Laboratories, within a web-enabled, cloud-based graphical user interface, termed A Rarefied gas, Industrial Simulation Tool On The cLoud Environment (ARISTOTLE). The Phase I effort entailed development of the prototype proof of concept version of ARISTOTLE. We demonstrated the feasibility of the ARISTOTLE concept by successfully leveraging the SPARTA library in a web-based cloud computing architecture. The prototype entails a cloud environment, which leverages Amazon Web Services’ (AWS) Elastic Cloud Compute (EC2) architecture for high performance computing (HPC) capabilities. Separate user accounts and basic user interfaces leveraged an expansive ‘Workflow’ module. This module enables execution of high-fidelity scientific software and libraries, such as SPARTA. During the Phase II, we have extended the Phase I prototype software. The ‘Workflow’ library has been extensively expanded and generalized to enable a wide range of computational needs. The ARISTOTLE website has been upgraded under the AWS-EC2 with the website mapped out to include interfaces for potential and current customers. The compute nodes have been transitioned to the Sabalcore high performance computing architecture to enable scalable ARISTOTLE applications for a wide range of customers. Automated algorithms that enable general users to leverage the SPARTA software effectively for detailed rarefied flow predictions have been developed and integrated within the ARISTOTLE simulation structure. These algorithms have been demonstrated for detailed gas flow predictions through a wide range of channel flows. The algorithms have been demonstrated to enable a novice user to reproduce published results performed by experts in the rarefied gas dynamics field. The tools have been beta-tested by a wide range of potential users, ranging from expert to novice level skills. Leveraging the appropriate interfaces, all users have been able to generate outputs of value for the specific application. The results have been shared with various customers and discussions on commercial applications are currently underway. The framework developed and demonstrated within this SBIR program will enable users across multiple industries to leverage DSMC capabilities to explore the design space for a number of industrial applications that require vacuum science. The results of this Phase II have enabled the development of a software capability that will be released as a commercial application in the future after the feedback from the beta-tests are fully integrated within the ARISTOTLE architecture.
