Remote CFD with OpenFOAM

Remote CFD with OpenFOAM

During travel and social restrictions, a CFD engineer can be productive by quickly switching to remote CFD using CFD Direct From the Cloud™ (CFDDFC®) and by learning effective CFD. CFDDFC is a turnkey system with OpenFOAM and supporting software running in its native Linux environment on AWS. Engineers can launch remote instances (virtual machines) in 2 minutes providing remote desktop access to 48 core instances and scalable clusters of 100s of cores. At the same time the engineer can learn to be more productive by registering for our Live Virtual OpenFOAM Training, taken from the safety and comfort of their home using the CFDDFC system.

CFDDFC v7.0 Released

CFDDFC v7.0 Released

CFD Direct is pleased to announce the release of version 7.0 of CFD Direct From the Cloud™ (CFDDFC), the leading marketplace product for CFD on Amazon Web Services. CFDDFC v7.0 includes OpenFOAM v7, ParaView v5.6.0, OpenMPI v3.1.4 and FreeCAD v0.18.3, running on Ubuntu 18.04 LTS. CFDDFC v7.0 supports Elastic Network Adapter and Elastic Fabric Adapter which provide higher network performance on C5n instances. This delivers good parallel scaling performance on clusters of instances up to 1000 cores. The command line interface includes new options from simple launch of clusters and monitoring of costs.


External Aerodynamics of a Vehicle with OpenFOAM

In November 2018, Amazon Web Services (AWS) announed Elastic Fabric Adapter, a network interface for HPC applications running on EC2. We previewed the EFA technology, running benchmark CFD simulations with OpenFOAM, presented previously: (1) strong scaling – 97 m total cells, external aerodynamics around a car; (2) weak scaling – 100 k cells per core, flow over a weir. At 1008 cores, EFA delivered linear scaling in the strong scaling test and ~70% scaling in the weak scaling test. With linear strong scaling, EFA enables faster solutions for the same cost simply by running on more cores. The combination of open source software, C5n instances and EFA provides impressive HPC, at a price accessible to all.

OpenFOAM HPC with AWS C5n

Flow over a Weir with Hydraulic Jump

CFD Direct From the Cloud™ (CFDDFC) is a Marketplace Product for AWS EC2, that provides a complete platform with OpenFOAM and supporting software running on Ubuntu Linux. It enables simple, fast creation of a cluster of instances to run CFD with OpenFOAM. We tested Amazon EC2 C5n instances, launched in November 2018, on 2 cases of steady-state, external aerodynamics around a car and transient simulation of water flowing over a weir. With meshes of 50-100 million cells, results showed 70%-90% scaling at 504 cores. The cost of the simulations was in the order of $100, compared to $100,000+ to purchase on-premises hardware and licences of proprietary software.


CFD Direct From the Cloud AWS C5/M5

CFD Direct From the Cloud (CFDDFC) is our established platform for running OpenFOAM, ParaView and supporting software using cloud computing. CFDDFC is now available on AWS C5 and M5 instances of Elastic Cloud Compute (EC2). The CFDDFC product page on AWS MarketPlace now lists CFDDFC versions 5.2 and 4.2, corresponding to versions 5 and 4 of OpenFOAM, respectively. Users who launch CFDDFC with the command line interface should update their installation of CFDDFC immediately.

Cloud CFD Course

CFD Direct announces the release of their new 1 day Cloud CFD course, the fourth course in their portfolio of OpenFOAM Training. The course enables users to run CFD with OpenFOAM on AWS, training the tools and processes for inexpensive, secure, efficient cloud use. The course addresses the main concerns of using public cloud: cost management, security, efficient CFD and data management. It exploits the cost benefits of cloud: meeting fluctuating demand for hardware at a cost that represents consistent, high utilitisation; and using cheaper, spare capacity, with an application that does not require 100% availability.
