COMSOL 6.2 - If, ElseIf, Else, EndIf

Construct an If statement, enabling or disabling features depending on conditions in terms of parameters.

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

model.component(<ctag>).geom(<tag>).createAfter(<ftag>,<type>,<postag>);

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>,<type>) to add an If, ElseIf, Else, or EndIf feature after the current feature.

Use model.component(<ctag>).geom(<tag>).feature().createAfter(<ftag>,<type>,<postag>) to add an If, ElseIf, Else, or EndIf feature after the feature tagged <postag>.

The following property is available for If and ElseIf only:

Table 3-90: Valid Property.
Name	Value	Default	Description
condition	double	1	Logical condition in terms of parameters.

Example

Build a block if variant = 1, else build a cone:

Code for Use with Java

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

model.param().set("variant", "1");

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

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

g.create("if1", "If");

g.feature("if1").set("condition", "variant==1");

g.create("blk1", "Block");

g.create("else1", "Else");

g.create("cone1", "Cone");

g.create("endif1", "EndIf");

g.run();

model.param().set("variant", "2");

g.run();

Code for Use with MATLAB

model = ModelUtil.create('Model1');

model.param.set('variant', '1');

model.component.create('comp1');

g = model.component('comp1').geom.create('geom1', 3);

g.create('if1', 'If');

g.feature('if1').set('condition', 'variant==1');

g.create('blk1', 'Block');

g.create('else1', 'Else');

g.create('cone1', 'Cone');

g.create('endif1', 'EndIf');

g.run;

model.param.set('variant', '2');

g.run;
