FreeQuad

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);

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:

Feature	Remarks
CornerRefinement	Used when generating mesh on faces. Only available when generating mesh for a geometry,
Distribution	Used when defined on edges.

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").
