Map

Create a structured (mapped) quadrilateral mesh. The mapped mesher maps a regular grid defined on a logical unit square onto each domain. The mapping method is based on transfinite interpolation.

Syntax

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

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

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

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

model.mesh(<tag>).feature(<ftag>).create(<ftag1>,ftype);

Description

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

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

The following properties are available:

Table 4-46: Available Properties

Property	Value	Default	Description
adjustedgdistr	on | off	off	When enabled, the mapped mesher adjusts evenly distributed edge mesh
continue	on | off	on	When enabled, the mesher does not stop if there is an error
interpmethod	auto | transfinite2D | transfinite3D	auto	Interpolation method (3D meshes only)
smoothcontrol	on | off	on	Specifies if the operation smooths the mesh across removed control entities
smoothmaxiter	integer	8 in 2D, 4 in 3D	Specifies the number of smoothing iterations
smoothmaxdepth	integer	8 in 2D, 4 in 3D	Specifies the maximum element smoothing depth

The following attribute features are used:

Table 4-47: 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.

Compatibility

The following properties from the corresponding COMSOL Multiphysics 3.5a command, meshmap, have been removed:

Property	Reason
edgelem	Defined by the Distribution
face	Defined by the selection
mcase	Defined by the meshing sequence
meshstart	Input mesh provided by meshing sequence
out	Output mesh provided by meshing sequence
domain	Defined by the selection
