FreeQuad
Create an unstructured quadrilateral mesh.
Syntax
model.component(<ctag>).mesh(<tag>).create(<ftag>,"FreeQuad");
model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection();
model.component(<ctag>).mesh(<tag>).feature(<ftag>).set(property,<value>);
model.component(<ctag>).mesh(<tag>).feature(<ftag>).getType(property);
model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,ftype);
Description
Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"FreeQuad") to create an unstructured quadrilateral mesh.
Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection() to specify the domain (boundary in 3D) selection. If you do not specify any selection the feature creates a mesh on the remaining geometric entities in 2D. In 3D, the default selection is empty.
Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,ftype) to add attribute features.
The following properties are available:

See the FreeTet feature for more information on the properties.
The following attribute features are used:
Table 4-43: Attribute Features for FreeQuad
Feature
Remarks
CornerRefinement
Used when generating mesh on faces. Only available when generating mesh for a geometry,
Distribution
Used when defined on edges.
Size
All properties are used.
SizeExpression
All properties are used. Only available when generating mesh for a geometry.
For imported meshes, there is a default size attribute under the FreeQuad feature with the tag size. You can access it using model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature("size").
