meshplot
Purpose
meshplot
Plot mesh.
Syntax
Description
meshplot(fem,...)
meshplot(mesh,...)
h = meshplot(...)
meshplot(fem,...) plots the mesh object fem.mesh.
meshplot(mesh,...) plots the mesh object mesh.
h = meshplot(...) additionally returns handles to the plotted axes objects.
The mesh of the PDE problem is specified by the mesh object. Details on the
representation of the mesh can be found in the entry femmesh.
There is a multitude of options that enables you to plot the mesh in virtually any
conceivable way. For 2D and 3D meshes, there are basically two types of mesh plots;
the wireframe plot and the patch plot.
In 3D, the default type is a patch plot, where both the triangular faces of the
elements and the boundary elements are rendered. Only the visible faces of the
elements are included in the plot, and the boundary elements and other mesh faces
are plotted in different colors. The characteristics of this plot type are controlled by
the properties that start with edge and bound. The edge properties control the plot
of the element faces, and the bound properties control the boundary element plot
(the name edge has historic reasons; it was first used in 2D). The color of the edges
of the element faces is determined by the property eledgecolor.
The alternative type of 3D plot is a wireframe plot, consisting of the (1D) edges of
the elements and the boundary elements. The properties that start with dedge and
dbound control the plot characteristics of this plot type. The dedge properties
control the plot of the element edges, and the dbound properties control the plot
of the edges of the boundary elements. See the 3D example below for how to obtain
a patch plot and a wireframe plot of a mesh. You can also plot the mesh edges that
lie on geometry edges (curves) with a special color. The characteristics of this plot
is controlled by the properties that begin with curve.
In 2D, there are basically two types of mesh plots. The default type is a wireframe
plot of the edges of the elements, where the boundary elements are plotted in a
different color. The properties that start with edge and bound control the plot
characteristics of this plot type. The edge properties control the plot of the element
edges, and the bound properties control the boundary element plot.
