Explain the snapping process.
 

Can anyone explain the snapping process along with the associated SnapControls?
The info in user guide is too little to get an insight, for a beginner like me.

Have a look at this pdf, which is a very comprehensive guide to snappyHexMesh. You can safely ignore the parts about HelyxOS if you don't use it.

@zordiack I have already gone through it. But sadly it has just two slide for explaining snapping process uner snapcontrols. I am not being able to understand clearly what the parameters there means. I have understood castellated process. Just like that ,they don't seem to have given indepth what actually happens under snapcontrol.

Also have a look at https://sites.google.com/site/snappy...ppyhexmeshdict.
