Selections

Most mesh features have selections, to specify where they operate. To access a feature’s selection, use the syntax

model.mesh(<tag>).feature(<ftag>).selection();

To specify the entire geometry, write

model.mesh(<tag>).feature(<ftag>).selection().allgeom();

To specify all geometric entities in dimension <dim>, write

model.mesh(<tag>).feature(<ftag>).selection().geom(<dim>).all();

To specify the geometric entities that remains to be meshed when the feature is about to be built, use

model.mesh(<tag>).feature(<ftag>).selection().remaining();

It is not possible to retrieve the geometric entities of this selection, unless the feature is built.

If entities is an integer array of geometric entities in dimension dim, use the following syntax to select these entities

model.mesh(<tag>).feature(<ftag>).selection().geom(dim).set(entities);

For example, to selection domain 1 and 2 in a 3D geometry, write

model.mesh(<tag>).feature(<ftag>).selection().geom(3).set(new int[]{1,2});

To add the geometric entities specified in the integer array <entities> in dimension <dim> to the selection, write

model.mesh(<tag>).feature(<ftag>).selection().geom(<dim>).add(<entities>);

To remove the geometric entities specified in the integer array <entities> in dimension <dim> from the selection, write

model.mesh(<tag>).feature(<ftag>).selection().geom(<dim>).remove(<entities>);

To clear the selection in dimension <dim>, write

model.mesh(<tag>).feature(<ftag>).selection().geom(<dim>).clear();

Some features have more than one selection, for example sweep, where it is possible to specify source and destination faces. Use the following syntax to access these selections.

model.mesh(<tag>).feature(<ftag>).selection(<property>);

Thus, to specify boundary 5 as source face on the sweep feature swe1, write

model.mesh(<tag>).feature(<ftag>).selection("sourceface").geom(2).set(5);
