Clustering points in IGG
 

Hi,
I'm kind of new at meshing with IGG, and was wondering what does it mean to cluster points at the face of a block and what is the benefit of doing so...

Some insight will be much appreciated.

Clustering will allow you to obtain smooth transition from very small cell width to larger cell width ensuring excellent expansion ratio between neighbor cells. It is useful to treat wall boundary layers and its extension in the wake of a wing.
