Map

Create a structured (mapped) quadrilateral mesh in domains in 2D and on faces in 3D. The mapped mesher maps a regular grid defined on a logical unit square onto each domain or face. The mapping method is based on transfinite interpolation. The operation can also be used to remesh meshes that define their own geometric model.

Syntax

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

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>,ftype);

Description

Use model.component(<ctag>).mesh(<tag>).create(<ftag>,"Map") to create a structured quadrilateral mesh.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).selection() to specify the domain (boundary in 3D) selection. If you do not specify any selection the feature creates a mesh on the remaining domains in 2D. In 3D, the default selection is empty.

Use model.component(<ctag>).mesh(<tag>).feature(<ftag>).create(<ftag1>,ftype) to add a Size, Distribution, or EdgeGroup attribute feature.

The following properties are available:

Table 4-25: Available Properties for map.
Property	Value	Default	Description
adjustedgdistr	on \| off	off	When enabled, the mapped mesher adjusts evenly distributed edge mesh.
interpmethod	auto \| transfinite2D \| transfinite3D	auto	Interpolation method (3D meshes only). Only available for meshes conforming with geometry.
smoothcontrol	on \| off	on	Specifies if the operation smooths the mesh across removed control entities. Only available for meshes conforming with geometry.
smoothmaxiter	integer	4	Specifies the number of smoothing iterations. Used if smoothcontrol is on.
smoothmaxdepth	integer	4	Specifies the maximum element smoothing depth. Used if smoothcontrol is on.

The following attribute features are used:

Table 4-26: Attribute Features Used.
Feature	Remarks
EdgeGroup	Defined on the domain/face to be meshed.
Distribution	Used when defined on edges.
Scale	Scales Size and Distribution.
Size	Defined on domain/face. Uses only hauto and hmax.
