meshmap
Purpose
meshmap
Create mapped quad mesh.
Syntax
Description
fem.mesh = meshmap(fem,...)
fem.mesh = meshmap(geom,...)
fem = meshmap(fem,'out',{'fem'},...)
fem.mesh = meshmap(fem,...) returns a mapped quad mesh derived from the
geometry fem.geom. For a 3D geometry, only the faces are meshed.
fem.mesh = meshmap(geom,...) returns a mapped quad mesh derived from the
geometry geom.
fem = meshmap(fem,'out',{'fem'},...) modifies the fem structure to include
a mesh in fem.mesh.
The quad mesh is generated by a mapping technique. For each subdomain in 2D
and face in 3D, a logical mesh is generated on a square geometry and is then mapped
onto the real geometry by transfinite interpolation.
The following criteria must be met by the input geometry object for the mapping
technique to work:
• Each subdomain/face to be meshed must be bounded by one connected
boundary component only.
• Each subdomain/face to be meshed must be bounded by at least four edges.
• The subdomains/faces to be meshed must not contain isolated vertices or edges.
• The shape of each subdomain/face to be meshed must not differ too much from
rectangular shape.
The function meshmap accepts the following property/values:
