meshextrude
Purpose
meshextrude
Extrude a 2D mesh object into a 3D mesh object.
Syntax
Description
fem1 = meshextrude(fem0,...)
[mesh,geom]= meshextrude(fem,’Out’,{’mesh’,’geom’},...)
fem1 = meshextrude(fem0,...) extrudes the 2D geometry object in fem0.geom
and the 2D mesh object in fem0.mesh, into a 3D geometry object and a 3D mesh
object stored in fem1.geom and fem1.mesh, respectively, according to the given
parameters.
[geom,mesh]= meshextrude(fem,’Out’,{’geom’,’mesh’},...) returns the
3D geometry object in geom and the 3D mesh object in mesh.
Valid property/value pairs for the meshextrude function are given in the following
table. In addition, all extrude parameters are supported and are passed to extrude
for creating the extruded 3D geometry object.
PROPERTY VALUES DEFAULT DESCRIPTION
Elextlayers 1-by-nd cell array Distribution of mesh element
layers in extruded mesh
Mcase integer 0 Mesh case number
Out fem | mesh | geom fem Output variables
The property Elextlayers defines the distribution of mesh element layers in the
extruded mesh. The value of Elextlayers is a cell array where each entry
corresponds to a section in the extruded geometry object. If a cell entry is a scalar,
it defines the number of equally distributed mesh element layers that is generated
for the corresponding extruded section. Alternatively, if a cell entry is a vector, it
defines the distribution of the mesh element layers for the corresponding extruded
section. The values in the vector, that are sorted and starts with 0, specify the
placements, in relative arc length, of the mesh element layers. Note that more
element layers might be introduced due to the division of the revolved geometry
into sections. By default, the number of element layers is determined such that the
distance of each layer is equal to the mean element size in the original 2D mesh.
Extruding a 2D mesh object into a 3D mesh object, the 2D vertex elements, the 2D
boundary elements, the 2D triangular elements, and the 2D quadrilateral elements,
are extruded into 3D edge elements, 3D quadrilateral boundary elements, 3D prism
elements, and 3D hexahedral elements, respectively.
Examples Create an extruded prism mesh on a cylinder of height 1.3.
