Midsurface

Generate a surface object that is the midsurface of a solid object in 3D.

Syntax

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

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>).
setAttribute(attribute,<value>);

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

Description

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

creates a Midsurface feature.

Use

model.component(<ctag>).geom(<tag>).feature(<ftag>).
selection("input")

to select the objects for the midsurface operation. The default selection is empty.

Table 3-55: Available properties
Property	Value	Default	Description
repair	on \| off	on	Repair overlaps
split	on \| off	off	Split in smooth components
createselection	on \| off	off	Create selections
contributeto	String	none	Cumulative selection to contribute to

For information about the createselection and contributeto properties, search the online help in COMSOL Multiphysics to locate and search all the documentation.

The following attributes are available:

Table 3-56: Valid attributes
Name	Value	Default	Description
construction	on \| off \| inherit	inherit	Designate the resulting objects as construction geometry. Use inherit to set the construction geometry attribute only if all input objects are construction geometry.

Example

Generate the midsurface of a thin block:

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

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

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

model.component("comp1").geom("geom1").geomRep("cadps");

model.component("comp1").geom("geom1").create("blk1", "Block");

model.component("comp1").geom("geom1").feature("blk1").
set("size", new String[]{"1", "1", "0.1"});

model.component("comp1").geom("geom1").
create("mid1", "Midsurface");

model.component("comp1").geom("geom1").feature("mid1").
selection("input").set(new String[]{"blk1"});

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