COMSOL 6.2 - IgnoreVertices

Ignore vertices by removing the selected vertices that are isolated or that are adjacent to precisely two edges.

model.component(<ctag>).geom(<tag>).create(<ftag>,"IgnoreVertices");

model.component(<ctag>).geom(<tag>).feature(<ftag>).selection(property);

model.component(<ctag>).geom(<tag>).feature(<ftag>).set(property,<value>);

model.component(<ctag>).geom(<tag>).feature(<ftag>).getType(property);

Use model.component(<ctag>).geom(<tag>).create(<ftag>,"IgnoreVertices") to ignore vertices.

Use model.component(<ctag>).geom(<tag>).feature(<ftag>).selection("input") to select the vertices to ignore. The default selection is empty.

The feature removes the selected vertices that are isolated or that are adjacent to precisely two edges. If a vertex is adjacent to two edges, the operation forms a composite edge. The output object is a virtual geometry.

The following properties are available:

Table 3-93: Valid Properties.
Name	Value	Default	Description
input	Selection		Vertices to ignore.
keepformesh	on \| off	off	Keep vertices for mesh control.

Use keepformesh to keep the ignored vertices while meshing, to help you in constructing the mesh.

Create an ellipse and ignore vertices 1 and 3, which gives you two remaining edges in the final geometry.

Code for Use with Java

Model model = ModelUtil.create("Model");

model.component().create("comp1");

GeomSequence g = model.component("comp1").geom().create("geom1", 2);

model.mesh().create("mesh1", "geom1");

g.create("e1", "Ellipse");

g.create("igv1", "IgnoreVertices");

g.feature("igv1").selection("input").set("fin", 1, 3);

Code for Use with MATLAB

model = ModelUtil.create('Model');

model.component.create('comp1');

g = model.component('comp1').geom.create('geom1', 2);

model.mesh.create('mesh1', 'geom1');

g.create('e1', 'Ellipse');

g.create('igv1', 'IgnoreVertices');

g.feature('igv1').selection('input').set('fin', 1, 3);
