OpenFOAM - Foundation Training

Learn how to apply OpenFOAM to setup , run, and post-process CFD problems on small cases.
Audience
CFD Engineers.
Prerequisites

Basic knowledge of Linux, C++, and Computational Fluid Dynamics (CFD) are beneficial

概要

This course includes an introduction to OpenFOAM environment. Participants undertake exercises in simulating cases and programming in OpenFOAM using ESI’s Cloud-based HPC computing platform. All work from the training will be stored on the cloud and participants may download all the work and exercises at the end of the training.This training doesn’t teach any programming or source code modifications.
