COMSOL 6.4 - Defeaturing Tools — Detect Interferences

Defeaturing Tools — Detect Interferences

Access the DetectInterferences tool by the command

GeomDefeature tool = model.component(<ctag>).geom(<tag>).defeaturing("DetectInterferences");

To access the input objects selection, use

GeomObjectSelection input = tool.selection("input");

To set the tolerance for detecting intersections, use

tool.set("abstol", value);

To set the tolerance for detecting gaps, use

tool.set("gaptol", value);

To find interferences, type

To access the resulting interferences, use

GeomObjectGroupSelection interf = tool.detail();

Each node listed in Interfering faces list in the user interface corresponds to a group of faces in GeomObjectGroupSelection. To access the data for a group, use its integer group index:

String label = interf.groupNames()[group];

String objName = interf.groupObject(group);

int[] faces = interf.groupEntities(group);

double gapSize = interf.entSize(group)[0];

The face numbers in the groups do not refer to the input objects. Rather, they refer to objects in a local state, where the tool has imprinted edges where objects interfere. To hide faces in the local state, first type

tool.localState(true);

to enter the local state. After doing the hiding, type

tool.localState(false);

to exit the local state.
