Hello OF world,

I made a mesh quality improvement / smoothing utility for OF. It moves internal mesh points by using the Centroidal smoothing algorithm (a version of the Laplacian smoothing algorithm, which uses surrounding cell centers instead of the neighbouring vertex locations to calculate the new vertex position). Optional heuristic quality control options exist to constrain the smoothing, to avoid self-intersections. No changes to mesh topology are made.

Code available at https://github.com/tkeskita/smoothMesh

Have a look at the demo video:

Cheers!

Hello OF world,

I've now reached a point where I think smoothMesh is stable. It can now also improve the prismatic boundary layers in the smoothing process. If you need mesh smoothing, please give it a go and comment in this thread how did it go. I added some run examples of a test case in the docs to show the usage. Happy smoothing!

Here's an example test mesh before smoothing:




and after smoothing:

Hi,
Can you tell me how to install this?

I have my Openfoam installed in:

/opt/openfoam12

I have downloaded your code and have kept it in the openfaom12 folder:

/opt/openfoam12/smoothMesh-main

Then from here how to go about installing it?

Hi,

sorry, it currently works only on openfoam.com v2412. Compilation instructions: https://github.com/tkeskita/smoothMe...n-instructions

I compiled and ran it on OpenFOAM.com v2212. Worked without modification.
