OpenFOAM Tutorial

If you’re new to OpenFOAM, there are several tutorials that can help you learn how to use the program. These include how to use PimpleFoam, DES, and OpenFOAM, as well as how to create a simulation from scratch. After reading these tutorials, you should be able to start working with OpenFOAM in no time.

OpenFOAM

In order to get the most out of OpenFOAM, you should first understand how the software works. Once you’ve learned how to run the software, you can start working on the different types of simulations it can perform. The OpenFOAM tutorial can help you get started. The tutorial includes test cases, as well as a variety of OpenFOAM utilities. These utilities will help you mesh the data and set up the simulations. You’ll also learn how to post-process the results using a graphics application, such as ParaView.

The OpenFOAM tutorial is organized in a step-by-step fashion. The tutorial includes several screencasts that walk you through the process of generating an OpenFOAM project from scratch. Throughout the tutorial, Tobias Holzmann shares his experience and provides tips and tricks. The tutorial is divided into nine different sub-topics.

PimpleFoam

PimpleFoam is an open-source solver for thermal and fluid flows. It can be used to simulate porous materials. The OpenFOAM solver takes several assumptions, including fluid properties, a porous region, and two phases. These are added to the source code.

OpenFOAM has many libraries that perform specific tasks in the CFD workflow. Examples of libraries include snappyHexMesh, simple form, and pimpleFoam. These libraries are available as open-source code, so you can modify and extend them as you wish.

DES

DES is a simulation method that combines the features of RANS and LES simulations. Its goal is to incorporate the most advantageous aspects of both. DES models are available in OpenFOAM. Unlike RANS, which only uses one mode, DES can switch between both modes.

A DES model has a finer spatial resolution than an LES model, allowing for a more detailed study of the flow. It is often used in industrial applications because it overcomes the limitations of RANS models. It is also less expensive than a full-fledged LES approach.
