meshrevolve
Purpose
meshrevolve
Revolve a 2D mesh object into a 3D mesh object.
Syntax
Description
fem1 = meshrevolve(fem0,...)
[mesh,geom]= meshrevolve(fem,’Out’,{’mesh’,’geom’},...)
fem1 = meshrevolve(fem0,...) revolves 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]= meshrevolve(fem,’Out’,{’geom’,’mesh’},...) returns the
3D geometry object in geom and the 3D mesh object in mesh.
Valid property/value pairs for the meshrevolve function are given in the following
table. In addition, all revolve parameters are supported and are passed to revolve
for creating the revolved 3D geometry object.
PROPERTY VALUES DEFAULT DESCRIPTION
elrevlayers scalar | vector Distribution of mesh element
layers in revolved mesh
mcase integer 0 Mesh case number
out fem | mesh | geom fem Output variables
The property elrevlayers defines the distribution of the mesh element layers in
the revolved mesh. If the value of elrevlayers is a scalar, it defines the number of
equally distributed mesh element layers in the revolved mesh. Alternatively, if
elrevlayers is a vector, it defines the distribution of the mesh element layers in the
revolved mesh. The values in the vector, that are sorted and starts with 0, specifies
the placements, in relative arc length, of the mesh element layers. By default, the
number of element layers is determined such that the distance of each layer is equal
to the mean size of the elements in the original 2D mesh.
Revolving 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 revolved into 3D edge elements, 3D quadrilateral boundary elements, 3D prism
elements, and 3D hexahedral elements, respectively.
Examples
Create a revolved prism mesh on a torus:
fem.geom = circ2(1,'pos',[2 0]);
fem.mesh = meshinit(fem);
fem1 = meshrevolve(fem);
