gradation command

Syntax

extrude mesh gradation f

Specify maximum gradation f > 0 for the unstructured mesher. The default value is 0.5.

This parameter controls the gradation of zone sizes from those specified on block boundaries to the size defined by target-size (see extrude mesh target-size) inside of the block. A value close to 0 leads to a more progressive variation of zone sizes (smoother).
