block zone generate-new command

Syntax

block zone generate-new keyword <range>

Primary keywords:

flowzone-new    gradation-surface    gradation-volume    maximum-edge    minimum-edge    number-control-points

Generate tetrahedral zones to fill blocks.

flowzone-new b

Set b to on to use new trangulation logic for flow zones. This may be necessary for blocks with large zone size gradations. Default is on.

gradation-surface f

Rate at which, on the surface of blocks, neighboring triangle sizes vary as triangles increase or decrease in size due to local size adaptation. This is a number from 0 to 1 with 0 being no gradation and 1 being maximum gradation.

gradation-volume f

Rate at which neighboring tetrahedra will increase in size away from the surface. This is a number from 0 to 1 with 0 being no gradation and 1 being maximum gradation.

maximum-edge f

Specify the maximum edge length for any tetra to be generated. The actual maximum edge length will be close to this, but the result is not guaranteed to be exact.

minimum-edge f

Specify the minimum edge length for any tetra to be generated. The actual minimum edge length will be close to this, but the result is not guaranteed to be exact.

number-control-points i

Specify the number of points on faces to which the specified edge size (block zone size) is specified. Increasing the number of control points produces a more uniform mesh. The default value is 5. See Generating Zones for an example.

Usage Example
