CFDDFC® v10 Released
CFD Direct is pleased to announce the release of version 10 of CFD Direct From the Cloud™ (CFDDFC®), available on Amazon Web Services (AWS) Marketplace as the standard CFDDFC product and CFDDFC (Arm). Standard CFDDFC v10 includes OpenFOAM v10, ParaView v5.6.0, OpenMPI v4.1.1 and FreeCAD v0.19.2, running on Ubuntu 20.04 LTS. CFDDFC (Arm) is server-only including OpenFOAM v10 and OpenMPI v4.1.1, running on Ubuntu 20.04 LTS. CFDDFC runs on single instances with up to 64 C6i Intel cores (c6i.32xlarge), 96 C6a AMD cores (c6a.48xlarge) or 64 C7g Graviton cores (c7g.16xlarge) and in clusters with with good parallel scaling on clusters of instances up to 1000 cores.
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.
Using NCC in OpenFOAM
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. This document describes how to use NCC to enable OpenFOAM users to transition from the AMI functionality to NCC. Due to its popularity, AMI remains in OpenFOAM for the next version 10 release in July 2022, but will thereafter be removed. The unreliable ACMI and Repeat AMI functionalities are removed.
