Run simulations at scale on AWS
CFD is the mainstay for engineers to improve product designs and rapidly develop viable prototypes

Computational fluid dynamics (CFD) on AWS allows you to run your simulations faster and run more of them simultaneously with no queues. Customers such as Formula 1, INEOS, Dallara, Joby Aviation and many more use AWS to accelerate their product design and innovate faster. It’s easy to get started, just follow our workshop for a step by step guide to launch an HPC cluster and start running popular codes like Siemens Simcenter STAR-CCM+, Ansys Fluent, and OpenFOAM.

Formula 1 Redesigns Cars for Closer Racing with AWS HPC

AWS CFD workshops

Learn how you can use some of the most popular CFD codes like Simcenter STAR-CCM+, OpenFOAM, Ansys Fluent on AWS with AWS ParallelCluster. Follow along to the workshops linked below, and use the example submission scripts to get started running your own CFD workloads on AWS. 

Dallara

Dallara case study

Using AWS, Dallara built an HPC system that met its benchmarks for performance and cost, leading the company to continue designing some of the world’s fastest and most aerodynamic vehicles such as Indy and Formula race cars.

How AWS' infrastructure takes your CFD to the next level

The flexibility of the AWS infrastructure means that whatever your CFD workload, from complex fluid flows involving turbulence to acoustics and electromagnetics, there’s an Amazon EC2 instance to suit. Intel Xeon processor-based instances such as C5n with Elastic Fabric Adaptor (EFA) ensure that up to 100 Gbps of bandwidth is made available for complex simulations. Flexible configuration and virtually unlimited scalability enable you to grow and shrink your infrastructure as your CFD workloads demand.

Enhancing CFD with Elastic Fabric Adapter

Elastic Fabric Adapter (EFA) is a network interface that relies on a custom-built OS-bypass technique to speed up communication between compute instances. It enables customers to scale their applications to tens of thousands of CPU cores. Advances in CFD algorithms enable engineers to simulate increasingly complex flows, and HPC helps reduce turn-around times. With EFA, design engineers can now scale out their simulation jobs to experiment with more tuneable parameters, leading to faster, more accurate results.
