Standard mesh |
Activates the Voronoi-Delaunay
meshing scheme for subsequent meshing operations. |
|
Curvature-based mesh |
Activates the curvature-based
meshing scheme for subsequent meshing operations. The mesher
creates more elements in higher-curvature areas automatically
(without need for mesh control). The curvature-based mesher supports
multi-threaded surface and volume meshing for assembly and
multibody part documents. The standard mesher supports only
multi-threaded volume meshing.
|
|
Blended
curvature-based mesh |
Activates the Blended curvature-based mesh. Use the
Blended curvature-based mesh for models that failed to mesh with
the standard or curvature-based mesh. The
Blended curvature-based mesh runs on a single central
processor unit (CPU) for surface and volume meshing that can
make the meshing process slower.
There are cases where the Blended curvature-based mesh can
overcome mesh failure, generating a solid mesh with
higher-quality elements (lower aspect ratios) than the
standard or the curvature-based mesh. The blended
curvature-based mesher supports h-adaptive and p-adaptive
methods.
The local mesh control
settings for the maximum element
size and minimum
element size should be within the range of
values you specify for the global mesh settings. Click
Calculate Minimum Element
Size to let the program calculate the
optimal value.

 |
Calculate Minimum
Element Size |
Available for the Blended
curvature-based mesh. Calculates the minimum element size based
on either the minimum radius of geometric curvature, or the
minimum element value set for mesh control.
- Include minimum radius of
curvature from geometry
- Include minimum element size
from mesh control
When you select both options, the program selects the
minimum of the two element size values. Click Apply to accept the calculated
minimum element size.

Unit |
Sets units for mesh sizes and
tolerance. |
 |
Global Size |
Available for standard mesh
only. Sets the global average element size. The software
suggests a default value based on the model volume and surface
area. |
|
Tolerance |
Available for standard mesh
only. Sets the tolerance value. The program calculates the mesh
tolerance value as the minimum of these quantities:
- 5% of the global element size (default
value)
- 30% of the smallest mesh element size
defined for mesh control definitions in the Mesh Control
PropertyManager
- The user-defined mesh tolerance value
in the Mesh
PropertyManager (if the user enters a value smaller than
the default mesh tolerance value)
If the distance between two nodes is smaller than this
value, the nodes are merged unless otherwise specified by
contact conditions. Adjusting the tolerance can help resolve some meshing
problems. For example, if meshing fails due to free edges,
increasing the tolerance can solve the
problem.

|
Automatic transition |
Available for standard mesh
only. When checked, the program automatically applies mesh
controls to small features, holes, fillets, and other fine
details of your model. Clear Automatic transition before meshing large
models with many small features and details to avoid generating
large numbers of elements. See example below. |
 |
Maximum element size |
Available for
curvature-based
mesh options only. The maximum element size is used for
boundaries with lowest curvature. |
 |
Minimum element size |
Available for curvature-based
mesh options only. The minimum element size is used for
boundaries with highest curvature. |
 |
Min number of elements in a circle |
Available for curvature-based
mesh options only. Specifies the number of elements in a circle.
To observe the effects of this option, the computed element size
must be between the Maximum element
size and Minimum
element size. See How Element Size Is
Determined. |
 |
Element size growth ratio |
Available for curvature-based
mesh options only. Specifies the global element size growth
ratio starting from regions of high curvatures in all
directions. |
