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

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

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);

Description

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"Distribution") to specify element distribution properties in the sequence. Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,"Distribution") to specify element distribution properties for the feature <ftag> that can be any of the types Edge, FreeQuad, FreeTri, FreeTet, Map, or Sweep.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection() or model.component(<ctag>).mesh(<tag>).feature(<ftag>).feature(<ftag1>).selection() to specify the edge or domain selection.

You can specify a mesh element distribution in three different ways: by specifying the number of elements only, by specifying the number of elements together with properties determining the distribution of the elements, or by specifying the element distribution explicitly. The property type determines which of the three alternatives you want to use. However, you need not set type manually since it is automatically updated when you set a property from one of the three groups below.

The following group of properties are available:

Table 4-36: Available Properties When Type is Number
Property	Value	Default	Description
numelem	integer	5	Number of elements.

Use the property numelem to specify the number of elements, but let the algorithm determine a suitable distribution, taking geometry and surrounding mesh into account.

Table 4-37: Available Properties When Type is Explicit
Property	Value	Default	Description
explicit	double[]	{0, 1}	Specifies the relative placement of vertices along the edge.
reverse	on \| off	off	Reverse the direction of the explicit distribution.

Use the explicit property to specify an explicit element distribution. The value of this property is an array with increasing values starting at 0.

Table 4-38: Available Properties When Type is Predefined
Property	Value	Default	Description
elemcount	integer	5	Number of elements.
elemratio	double	1	Specifies the ratio in size between the last element and first element along the edge.
method	arithmetic \| geometric	arithmetic	Specifies if the element distribution is an arithmetic or a geometric sequence.
reverse	on \| off	off	Specifies if the distribution is defined in the opposite edge direction for the edge in the selection with lowest index.
symmetric	on \| off	off	Specifies if the distribution is made symmetric.

When the type is predefined, the distribution as calculated from the parameters given above.

This Distribution feature can be assigned to edges in 2D and 3D, domains in 3D or the entire geometry. The FreeTet, FreeTri, FreeQuad, Edge, and Map features use this property on when defined on edges, the Sweep feature uses this property defined on domains.
