COMSOL 6.4 - DeleteFillets

DeleteFillets

Find and delete fillets in CAD objects.

Syntax

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

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);

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

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

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").selection(property);

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").set(property,<value>);

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").find();

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").detail();

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").delete(<ftag>);

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").deleteAll(<ftag>);

Description

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").delete(<ftag>)

creates a DeleteFillets feature tagged <ftag> with the specified properties. The property delete is set to selected. If the feature can be built, it is inserted in the geometry sequence after the current feature; otherwise, the feature is discarded.

model.component(<ctag>).geom(<tag>).defeaturing("Fillets").deleteAll(<ftag>) works as the delete method, but the property delete is set to all.

It is also possible to create the DeleteFillets feature using the standard create method. The following properties are available.

Table 4-6: Available Properties.
Property	Value	Default	Description
delete	all \| selected	selected	Delete all fillets of given size, or a selection. Only available for the feature.
minentsize	double	0	Minimum fillet radius.
entsize	double	1e-3	Maximum fillet radius.
input	Selection		Names of input objects.
selresult	on \| off	off	Create selections of all resulting objects.
selresultshow	all \| obj \| dom \| bnd \| edg \| pnt \| off	dom	Show selections of resulting objects in physics, materials, and so on, or in part instances. obj is not available in a component’s geometry. dom, bnd, and edg are not available in all features.
contributeto	String	none	Tag of cumulative selection to contribute to.

model.component(<ctag>).geom(<tag>).feature(<ftag>).find() searches the input objects for fillets with radius less than entsize.

model.component(<ctag>).geom(<tag>).feature(<ftag>).detail() returns a selection object where you can select a subset of the fillets found.

The find and detail methods of

model.component(<ctag>).geom(<tag>).defeaturing("Fillets")

have the corresponding functionality for the defeaturing tool.

Only faces that can be deleted without invalidating the object are deleted. If a fillet was not possible to delete, a warning is given, accessible through model.geom(<tag>).feature(<ftag>).problem().

Compatibility

The following property is no longer supported:

Example

The following example imports the CAD object in the COMSOL Multiphysics geometry file defeaturing_demo_3.mphbin and finds all fillets with radius less than 4·10−3. The first of these fillets is deleted.

Model model = ModelUtil.create("Model1");

model.component.create("comp1");

model.component("comp1").geom().create("geom1",3);

model.component("comp1").geom("geom1").feature().create("imp1","Import");

model.component("comp1").geom("geom1").feature("imp1").set("filename", "defeaturing_demo_3.mphbin");

model.component("comp1").geom("geom1").run("imp1");

model.component("comp1").geom("geom1").feature().create("dfi1","DeleteFillets");

model.component("comp1").geom("geom1").feature("dfi1").selection("input").set("imp1");

model.component("comp1").geom("geom1").feature("dfi1").set("entsize",4e-3);

model.component("comp1").geom("geom1").feature("dfi1").find();

model.component("comp1").geom("geom1").feature("dfi1").detail().setGroup(1);

model.component("comp1").geom("geom1").run();
