model.component(<ctag>).selection(<tag>) returns a named selection. Anywhere where you define a selection, you can point to a named selection by using its tag, for example, selection.named(<tag>.

model.component(<ctag>).selection().create(<tag>) creates a named selection of type Explicit.

model.component(<ctag>).selection().create(<tag>,<type>) creates a named selection of type <type>. The following types are available: "Explicit", "Union", "Intersection", "Difference", "Complement", "Adjacent", "Ball", "Box", "Cylinder", "Disk", and "LogicalExpression".

model.selection(<tag>).model(<mtag>) sets  the model component node of the selection.

model.selection(<tag>).model() returns the model component node tag of the selection.

model.component(<ctag>).selection(<tag>).set(property,<value>) sets a property value for the selection. Which properties are available for the different selection types are listed on the following pages. All other assignment methods are only supported by the Explicit selection type.

Use the model.selection(<tag>).image() methods for plotting and exporting selection images. See Plotting and Exporting Images.

All other methods are explained in the section Selections.

Other entities can use any of the selections in model.component(<ctag>).selection() when defining its selection. For example, create a selection sel1:

with highDim set to sdim and lowDim set to sdim-1 to select outputs boundaries that are adjacent to the selected domains. The typeList argument determines the types of adjacent boundaries included:

Listing both exterioroutside and exteriorinside is equivalent to just listing exterior.

When groupcontang is set to on, the set, add, and remove methods operate on groups of adjacent entities that have continuous tangents at their junctions.

The angletol property defines the tolerance for the continuity evaluation.

The posx, posy, and posz properties define the center of the ball, and r defines the radius. These properties take their units from the corresponding geometry sequence.

When condition is intersects, all entities that intersect the ball are included in the selection. The rendering mesh is used for the calculation. You can set the accuracy of the rendering mesh using

where <detail> is coarse, normal, fine, or wireframe.

When condition is inside, all entities that are completely inside the ball are included in the selection. The rendering mesh is used for the calculation.

When condition is somevertex, all entities that have at least one adjacent vertex inside the ball are included in the selection.

When condition is allvertices, all entities that have all adjacent vertices inside the ball are included in the selection.

When inputent is selections, the selection is restricted to the entities in the selections defined by the input property. When inputent is all, all entities in the geometry are considered.

When groupcontang is set to on, the selection operates on groups of entities that have continuous tangents at their junctions.

The angletol property defines the tolerance for the continuity evaluation.

The xmax, xmin, ymax, ymin, zmax, and zmin properties define the box. These properties take their units from the corresponding geometry sequence.

When condition is intersects, all entities that intersect the box are included in the selection. The rendering mesh is used for the calculation. You can set the accuracy of the rendering mesh using

where <detail> is coarse, normal, fine, or wireframe.

When condition is inside, all entities that are completely inside the box are included in the selection. The rendering mesh is used for the calculation.

When condition is somevertex, all entities that have at least one adjacent vertex inside the box are included in the selection.

When condition is allvertices, all entities that have all adjacent vertices inside the box are included in the selection.

When inputent is selections, the selection is restricted to the entities in the selections defined by the input property. When inputent is all, all entities in the geometry are considered.

When groupcontang is set to on, the selection operates on groups of entities that have continuous tangents at their junctions.

The angletol property defines the tolerance for the continuity evaluation.

The pos property defines the center of the cylinder and the axis property defines the cylinder axis. The top, bottom, r, and rin properties define the size of the cylinder. Setting rin equal to r corresponds to a cylindrical surface. These properties take their units from the corresponding geometry sequence. Using the angle1 and angle2 properties, you can create a cylinder segment.

When condition is intersects, all entities that intersect the cylinder are included in the selection. The rendering mesh is used for the calculation. You can set the accuracy of the rendering mesh using

where <detail> is coarse, normal, fine, or wireframe.

When condition is inside, all entities that are completely inside the cylinder are included in the selection. The rendering mesh is used for the calculation.

When condition is somevertex, all entities that have at least one adjacent vertex inside the cylinder are included in the selection.

When condition is allvertices, all entities that have all adjacent vertices inside the cylinder are included in the selection.

When inputent is selections, the selection is restricted to the entities in the selections defined by the input property. When inputent is all, all entities in the geometry are considered.

When groupcontang is set to on, the selection operates on groups of entities that have continuous tangents at their junctions.

The angletol property defines the tolerance for the continuity evaluation.

The posx and posy properties define the center of the disk, and r and rin define the outer and inner radius, respectively. These properties take their units from the corresponding geometry sequence. Using the angle1 and angle2 properties, you can create a disk segment.

When condition is intersects, all entities that intersect the disk are included in the selection. The rendering mesh is used for the calculation. You can set the accuracy of the rendering mesh using

where <detail> is coarse, normal, fine, or wireframe.

When condition is inside, all entities that are completely inside the disk are included in the selection. The rendering mesh is used for the calculation.

When condition is somevertex, all entities that have at least one adjacent vertex inside the disk are included in the selection.

When condition is allvertices, all entities that have all adjacent vertices inside the disk are included in the selection.

When inputent is selections, the selection is restricted to the entities in the selections defined by the input property. When inputent is all, all entities in the geometry are considered.

When groupcontang is set to on, the selection operates on groups of entities that have continuous tangents at their junctions.

The angletol property defines the tolerance for the continuity evaluation.

Define the selection equ1 as the domain of a rectangle and the selection bnd1 as the boundary of the rectangle.
