COMSOL 6.3 - CornerProp

To override the corner settings of BndLayer for a selection of corners.

model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"CornerProp");

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection();

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).
set(property,<value>);

model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).getType(property);

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"CornerProp") to override the corner settings for the feature <ftag> that can be of the type BndLayer.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection() to specify the vertex selection in 2D and the vertex or edge selection in 3D. The selection is empty by default.

The following properties are available:

Table 4-26: Valid Properties.
Name	Value	Default	Description
cornerhandling	trim \| split \| none	trim	Specify how to handle sharp corners for vertices in 2D and edges in 3D.
cornerhandlingvtx	trim \| none	trim	Specify how to handle sharp corners for vertices in 3D. Used if the parent BndLayer feature has a domain selection.
splitcondition	on \| off	off	Specify if to use an angle condition for the split. Used if cornerhandling is split. Not supported for vertices in 3D when the parent BndLayer feature has a domain selection.
splitdivangle	double	100	Maximum angle for split. Used if cornerhandling is split.
splitminangle	double	240	Split for angles greater than specified value. Used if splitcondition is on.
trimcondition	on \| off	off	Specify if to use angle conditions for the trimming. Used if cornerhandling is trim. Not supported for vertices in 3D when the parent BndLayer feature has a domain selection.
trimmaxangle	double	50	Trim for angles less than specified value. Used if trimcondition is on.
trimminangle	double	240	Trim for angles greater than specified value. Used if trimcondition is on.

It can be useful to filter out the corners of CornerProp in a CornerRefinement feature to either include them in the refinement if trim is used, or to exclude them if split or none is used.
