Overview
Web CFD Direct From the Cloud (CFDDFC) is a complete platform providing OpenFOAM (open source computational fluid dynamics) and supporting software running a long-term support (LTS) version of Ubuntu Linux. Users connect to an instance with a remote desktop from a web browser, and by SSH. OpenFOAM (Open Field Operation and Manipulation) is a free, open source CFD software package which has a large user base across most areas of engineering and science, from both commercial and academic organizations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics. It includes tools for meshing, notably snappyHexMesh, a parallelized mesher for complex CAD geometries, and for pre- and post-processing. Almost everything (including meshing, and pre- and post-processing) runs in parallel as standard, enabling users to take full advantage of computer hardware at their disposal.
Highlights
- Turnkey Installation of OpenFOAM
- Desktop Access from a Web Browser
- Enables Pay-as-you-go Scalable Parallel Computation

Dimensions summary
You pay by the hour for each running instance, with no upfront commitment or long-term contract. The software fee is billed alongside the separate AWS charges for the virtual server you choose. Each dimension matches a specific x86 compute or HPC instance type across several processor families and sizes. Smaller sizes (large, xlarge) carry lower hourly rates; larger sizes (such as 48xlarge and metal) carry higher rates reflecting more cores. You select the instance that fits your simulation, run it, then stop it. Charges apply only while an instance runs, matching the fluctuating demand of CFD work.
Top-of-mind questions for buyers
Each unit is one running EC2 instance of the named type, charged per hour of run time. The software fee is a small charge on top of the separate AWS costs for the virtual server, data storage, and data transfer. You pay both while the instance runs.
The software fee meters running time only, so a stopped instance stops accruing it. Charges begin when you launch an instance and end when you terminate it. Underlying AWS storage you leave provisioned can still incur separate fees until released.
Choose an instance that fits your simulation size; larger sizes give more cores at higher hourly rates. A single instance runs on up to 192 cores. You can also cluster instances to reach 1000 cores or more, with each running instance billed separately.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
