BndLayerProp

Set the boundary layer meshing properties.

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

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>,"BndLayerProp") to define boundary layer properties for the BndLayer feature <ftag>.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection() to specify the boundary or edge selection. If you do not specify the selection, it is empty.

The following properties are available:

Table 4-16: Available Properties.
Property	Value	Default	Description
blnlayers	Integer	8	Number of boundary layers
blstretch	Double	1.2	Boundary layer stretching factor
inittype	blhminfact \| blhmin \| blhtot	blhminfact	Specifies how the thickness of the boundary layer mesh is calculated.
blhminfact	Double	1	Factor used to adjust the default thickness. Used when inittype is blhminfact.
blhmin	Double		Thickness of first boundary layer. Used when inittype is blhmin.
blhtot	Double		Total thickness of the boundary layer mesh. Used when inittype is blhtot.

The value of blnlayers is a positive integer scalar, or a string that evaluates to a positive integer.

The values of blhmin, blhminfact, blhtot, and blstretch are positive real scalars, or strings that evaluate to positive real scalars.

Use the properties blhmin, blstretch, and blnlayers to specify the distribution of the boundary layers. blhmin specifies the thickness of the initial boundary layer, blhtot specifies the total thickness of the boundary layer mesh, blstretch a stretching factor, and blnlayers the number of boundary layers. The thickness of the mth boundary layer (m=1 to blnlayers) is blstretch(m−1)blhmin. The number of boundary layers and the thickness of the boundary layers might be automatically reduced in thin regions.

The default values of blhmin and blhtot are determined from the specified element size in the sequence.

It is also possible to specify the thickness of the initial layer by using the blhminfact property. Use this property to specify a scaling factor that multiplies the thickness of the first boundary layer.

The property inittype determines which of blhminfact, blhmin, or blhtot that is used. You do not need to set it explicitly because the feature automatically changes it when you set one of blhminfact, blhmin, or blhtot.
