Web CFDDFC® Released

CFD Direct is pleased to announce the release of Web CFD Direct From the Cloud (CFDDFC®), providing OpenFOAM via a remote desktop in a web browser, running on Amazon Web Services (AWS). Web CFDDFC is a pay-as-you-go Amazon Machine Image (AMI) from AWS Marketplace, providing a full desktop environment with graphical applications, including OpenFOAM v10, ParaView v5.6.0, OpenMPI v4.1.1 and FreeCAD v0.19.2, running on Ubuntu 20.04 LTS. Web CFDDFC runs on single instances with up to 64 C6i Intel cores (c6i.32xlarge) or 96 C6a AMD cores (c6a.48xlarge), and in clusters with with good parallel scaling on clusters of instances up to 1000 cores.

Effective OpenFOAM Maintenance

OpenFOAM is the leading free, open source software for computational fluid dynamics (CFD), distributed by The OpenFOAM Foundation. In 2014, OpenFOAM had accumulated significant “technical debt” due to a drive for new functionality at the expense of maintenance. Facing an unsustainable level of technical debt, CFD Direct was founded to manage and develop OpenFOAM back to a sustainable position. Code repair has targeted niche functionality that receives less testing. Redesign of larger, critical components of OpenFOAM has eliminated clusters of issues. By 2022, CFD Direct has recovered most of the technical debt, making OpenFOAM significantly more robust, usable and extensible.

OpenFOAM v10 Training

In Autumn 2022 – Spring 2023, CFD Direct is running its OpenFOAM Training courses — Essential CFD, Applied CFD and Programming CFD — fully updated with the latest features of the new version 10 release of OpenFOAM. The training uses new features in OpenFOAM v10 for more productive and effective CFD. All courses are delivered as live virtual training. Essential and Applied CFD courses are available: 19 – 23 Sep, 3-7 Oct, 6-10 Feb (2023), 13-17 Mar. Programming CFD is available 17-19 Oct, 1-3 Nov, 24-26 Jan (2023), 28 Feb-2 Mar, 28-30 Mar.

OpenFOAM Non-Conformal Coupling

In May 2022, CFD Direct released Non-Conformal Coupling (NCC) in OpenFOAM to connect regions of a domain with independent meshes for applications including rotating geometry. NCC is a robust replacement for the Arbitrary Mesh Interface (AMI) and associated ACMI and Repeat AMI functionalities. Unlike the AMI functionalities, NCC ensures conservation which is essential for accuracy but also for stability, in particular in numerical schemes designed to maintain boundedness, e.g. in multiphase flows. NCC naturally works for partially-overlapping geometries, as illustrated by the case of opening and closing of a three port ball value.
