Default Growth Rate

This section describes the properties that you can set for the Default Growth Rate.

If the Size Dependent Growth Rates is set to Small and large cells, for the Trimmed Cell Mesher meshing model (see Trimmed Cell Mesher Reference), the Volume Growth Ratenode has no properties of its own. Instead, it has two child nodes, one for the Default Growth Rate, and another for the Surface Growth Rate.



Properties on these nodes give a finer level of control over cell size transitions than is possible with the Size Dependent Growth Rates options on the Trimmed Cell Mesher node.

Properties of the Default Growth Rate

Small Cell Cutoff Size Type

Sets the size type for the cutoff size.

Relative to Base

Set the small cell cutoff size relative to the base size.

Absolute

Set the small cell cutoff size as absolute value with length units.

Default Growth Rate

This option controls the stepping from one cell size to the next within the core mesh. This option can be thought of as non-feature, far field growth control for the core mesh.

Fast

Default setting, which means that the fastest transition from the smallest cell size to the largest is used. This setting usually equates to having only one layer of each cell size for each transition, which results in the least number of cells being created for the supplied input values.

Medium

Gives a minimum of two equal sized cell layers per transition.

Slow

Gives a minimum of four equal sized cell layers per transition.

Very Slow

Gives a minimum of eight equal sized cell layers per transition.

Custom

Adds a Custom Default Growth Rate node on which to set a user-defined number of cell layers per transition.

Small Cell Growth Rate

This growth rate determines the growth rate in the vicinity of small cells in the template that are less than or equal to the cutoff size.

Fast

Default setting, which means that the fastest transition from the smallest cell size to the largest is used. This setting usually equates to having only one layer of each cell size for each transition, which results in the least number of cells being created for the supplied input values.

Medium

Gives a minimum of two equal sized cell layers per transition.

Slow

Gives a minimum of four equal sized cell layers per transition.

Very Slow

Gives a minimum of eight equal sized cell layers per transition.

Custom

Adds a Custom Small Cell Growth Rate node on which to set a user-defined number of cell layers per transition.
