[Other] Mesh quality visualization in paraview

Lieven · March 1, 2018, 06:28

Hi all,

We just released a small tool for OpenFOAM-5.x which analyzes the mesh quality and stores the cell/face non-orthogonality and skewness as fields:

Watch our tutorial on YouTube movie to see how it can be used: https://youtu.be/6fPnS0Ce5XQ

Cheers,

Hi Lieven,

This looks really useful and upon watching the video decided to go about building my own open foam 5.x to try this out, however, being new to this I am a bit unsure about the process of building openfoam with this tool. I currently have a working build of OpenFOAM 5.x and have tested it to work. The git page says that the tools are installed in $FOAM_USER_APPBIN, do I need to manually put something there? and if so what? apologizes if this seems basic, alternatively if there is some documentation for this that would be really helpful.

Many thanks,
Darren

In OpenFOAM 1712 you can also just use checkMesh -writeAllFields to write out all quality metrics or or -writeFields ... to only write specific ones (serial or parallel).

This worked well and was exactly what I was looking for, cheers!
