Setting Sizing Options

When creating a mesh, you can use the settings in the Mesh options panel to define the global element sizing and behavior for an object, a group of objects, or the entire model. Depending on the meshing context that you select, you can define settings for solids, surfaces, or both.

The following settings define the global element sizing and behavior:

• Element size

  The Element size is the maximum size of element to be generated. This setting drives the mesh seeding of the volume or surface mesh.

• Defeature size

  By default, mesh-based defeaturing is applied automatically to exclude small features and dirty geometry from the mesh. Any features smaller than or equal to the Defeature size are ignored when the mesh is generated. You can use the default setting, define your own Defeature size, or turn off defeaturing globally or selectively.

• Growth rate

  The Growth rate controls the increase in 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. The growth rate is primarily used when using tet mesh in free blocks.

• Growth height

  The Growth height specifies the first height of elements coming away from the selected face into the volume.
