Deep-dive into Ansys Fluent performance on Ansys Gateway powered by AWS

By Dnyanesh Digraskar, Principal HPC Partner Solutions Architect, AWS, Ashwini Kumar, Senior Principal Engineer, Ansys, Nicole Diana, Director, Fluids Business Unit, Ansys

January 1, 2024

Today, we’re going to deep-dive into the performance and associated cost of running computational fluid dynamics (CFD) simulations on AWS using Ansys Fluent through the Ansys Gateway powered by AWS (or just “Ansys Gateway” for the rest of this post).

Ansys Gateway is an AWS Marketplace hosted solution for users to manage their complete Ansys virtual desktop and HPC simulation workflows with more than fifty Ansys products in their AWS cloud environment. Emirates Team New Zealand and Turntide Technologies use Ansys Gateway to accelerate their design and engineering simulation cycles.

Ansys Fluent, an advanced physics modeling simulation software is used by engineers and scientists across industries like automotive, aerospace, manufacturing, and energy to innovate and optimize product development.

In this post, we’ll evaluate the performance and price characteristics for three test cases on various configurations of Amazon Elastic Compute Cloud (Amazon EC2) instance types. Using the results in this post, you’ll be able to make appropriate hardware choices for running Ansys Fluent simulations.

Ansys Gateway recap

Ansys Gateway is a secure, online platform that enables users to create, manage, and execute complete computer-aided engineering (CAE) workflows in their own AWS accounts. Earlier this year, we published a blog post that described solution architecture components, security implementation, and typical end-user workflows for using Ansys Gateway.

The Ansys applications (solvers) available through Ansys Gateway are pre-configured, validated, and extensively benchmarked on various Amazon EC2 hardware for performance and price. Ansys users can refer to the recommended usage guidelines on the Ansys Gateway documentation in Ansys Help to setup their virtual desktop infrastructure (VDI) or HPC environment with the recommended Amazon EC2 instance types. Users can then carry out simulations with solvers of their choice straight out-of-the-box without the need to manually setup and tune the solvers, simulation environment, and hardware parameters.
