checkMesh ∇ OpenFOAM® Application Training
Channel: Holzmann CFD
Date: 08/01/2020

In this brief introduction video, we are talking about the application named checkMesh. As József Nagy already has such a video published, please do not define it as a copy. The main intention in the video is to introduce you to the extension I made for the checkMesh application. 



The video is based on an already available OpenFOAM® tutorial, thus, everybody can redo it. During the execution of the checkMesh application, different outputs are written to the terminal. Most of them are explained and interesting hints and information are given during the video. 



As the checkMesh application in its basic implementation does not allow us to write out different mesh quality fields (as it is possible in the ESI version), I implemented an extension that creates new fields that can be post-processed in ParaView. Some examples are:

- non-orthonality for cells and faces
- skewness for cells and faces
- aspect ratio for cells
- volume for cells
- area of faces
- cell types (hexahedron, polyhedron, tet-wedges, ... and so on)

The extension I am talking about can be downloaded from my website and is built for the OpenFOAM® Foundation version. Please check the following link if you are interested: https://holzmann-cfd.com/en/openfoam/applications/checkmesh

Keep foaming and I hope you can get new information out of that video.
