Computational Fluid Dynamics
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.

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.
