CreateEdges

Create edges in a mesh that defines its own geometric model.

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

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);

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"CreateEdges") to create additional edges in a mesh that defines its own geometric model. For more information, see Geometric Model.

Choose between creating new meshed edges between vertices or converting existing mesh edges into edge elements. In the general case, converting mesh edges is most easily done by clicking in the Graphics window, as the midpoint coordinates must be exact.

When specifying start/end vertices, specify the size distribution in four different ways: by specifying the number of elements only, by specifying the maximum element size, by specifying the element distribution explicitly, or by specifying the number of elements together with properties determining the distribution of the elements. The property type determines which of the four alternatives you want to use.

The following properties are available:

Table 4-27: Available Properties for CreateEdges.
Property	Value	Default	Description
edgespec	vertices \| meshedge	vertices	Specifies how to create edges. Either give selections of start/end vertices, or give exact coordinates of a mesh edge’s midpoint.
start	Selection		Starting vertices to create edges from when edgespec is vertices.
end	Selection		End vertices to create edges to when edgespec is vertices.
type	size \| number \| explicit \| predefined	size	Size distribution type when edgespec is vertices.
coordsel	double[][]	{}	Enter exact midpoint coordinates of mesh edge when edgespec is meshedges.
seledg	on \| off	on	Specifies if to create a selection of resulting edges.

Table 4-28: Available Additional Property When type is SET to size.
Property	Value	Default	Description
size	double	0.1*(size of bounding box) (3D); (size of bounding box) / 15 (2D)	Maximum element size.

Table 4-29: Available Additional Property when type is number.
Property	Value	Default	Description
numelem	integer	1	Number of elements.

Table 4-30: Available Additional Properties when type is explicit.
Property	Value	Default	Description
explicit	double[]	{0,1}	Specify the relative placement of vertices along the edge.
reverse	on \| off	on	Reverse the direction of the explicit distribution.

Table 4-31: Available Additional Properties when type is predefined.
Property	Value	Default	Description
elemcount	integer	5	Number of elements.
elemratio	double	1	Specify the ratio in size between the last element and first element along the edge.
method	arithmetic \| geometric	arithmetic	Specifies if the element size is linearly growing (arithmetic sequence) or exponentially growing (geometric sequence).
reverse	on \| off	off	Specify if the distribution is defined in the opposite edge direction for the edge in the selection with lowest index.
symmetric	on \| off	off	Specify if the distribution is made symmetric.

Table 4-32: Available Additional Property When seledg are SET to on.
Property	Value	Default	Description
seledgshow	on \| off	on	Show edge selection in physics, materials, and so on. For mesh parts, this option shows selection outside the part. Used if seldom is on.
