The CFDDFC Command Line Interface

We provide a command line interface (CLI): 1) to manage instances of CFDDFC on Amazon Web Services (AWS); 2) transfer CFD cases to and from instances; 3)  run OpenFOAM applications on the instances; 4) connect to instances via a remote desktop.  Users can conveniently launch and terminate instances, check instance state and costs incurred from running CFDDFC.  They can transfer OpenFOAM case files to an instance, list the files on an instance and transfer results back to their local machine.  They can run OpenFOAM applications on the instance either remotely, by SSH login via a terminal or by remote desktop. The CLI provides a convenient way of launching clusters and can take advantage of enhanced networking using EFA.

Supported Operating Systems

The CFDDFC CLI is a collection of shell scripts that should run natively on Linux and macOS. The scripts should also run on Windows 10 using Windows Subsystem for Linux (WSL).

Dependent Software: AWS CLI

The CFDDFC CLI requires an installation of the AWS CLI to interface to connect with AWS via the terminal. Currently, we recommend installing the AWS CLI using the bundled installer but installation with pip is an effective alternative.  We do not recommend installation through standard repository packages, e.g. using apt-get on Debian/Ubuntu, because those packages can be out of date.  Note for Windows 10: the AWS CLI must be installed under Linux within Bash on Ubuntu on Windows.
