Growth Rate represents the increase in element edge length with each succeeding layer of elements. For example, a growth rate of 1.2 results in a 20% increase in element edge length with each succeeding layer of elements. This option is available when Use Adaptive Sizing is set to No. Specify a value from 1 to 5 or accept the default.

The default is calculated based on the Physics Preference option and the presence of sheet bodies.
