BndLayer

Create a boundary layer mesh.

model.component(<ctag>).mesh(<tag>).create(<ftag>,"BndLayer");

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

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

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

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

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"BndLayer") to create a boundary layer mesh in 2D or 3D.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection() to specify the domain selection. If you do not specify the selection, the feature operates on all domains.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"BndLayerProp") to add a BndLayerProp attribute feature defining the locations and properties of the boundary layers.

The feature reads properties from the BndLayerProp attribute feature.

The following properties are available:

Table 4-16: Available Properties for BndLayer
Property	Value	Default	Description
sharpcorners	none \| split \| trim	split	Specifies the handling of sharp corners in 2D and sharp edges in 3D.
splitangle	double	240[deg]	Minimum angle between boundary layer boundaries to introduce a boundary layer split.
splitdivangle	double	100[deg]	Maximum angle per split.
trimmaxangle	double	50[deg]	Maximum angle between boundary layer boundaries for boundary layer trimming.
trimminangle	double	240[deg]	Minimum angle between boundary layer boundaries for boundary layer trimming.
layerdec	integer	2	Maximum difference in number of boundary layers between neighboring points on boundary layer boundaries.
smoothtransition	on \| off	on	Specifies if the operation smooths the transition to interior mesh.
smoothmaxiter	integer	8 in 2D, 4 in 3D	Specifies the number of smoothing iterations.
smoothmaxdepth	integer	16 in 2D, 6 in 3D	Specifies the maximum element smoothing depth.

Insert boundary layers to an existing mesh containing both quadrilateral elements and triangular elements.
