Select Parameters from the Mesh menu to open the following dialog box containing mesh generation parameters.
The parameters used by the mesh initialization algorithm are:
Maximum edge size: Largest triangle edge length (approximately). This parameter is optional and must be a real positive number.
Mesh growth rate: The rate at which the mesh size increases away from small parts of the geometry. The value must be between 1 and 2. The default value is 1.3, i.e., the mesh size increases by 30%.
Mesher version: Choose the geometry
R2013a is faster,
and can mesh more geometries.
the same mesh as previous toolbox versions.
Jiggle mesh: Toggles automatic jiggling of the initial mesh on/off.
The parameters used by the mesh jiggling algorithm are:
Jiggle mode: Select a jiggle
mode from a pop-up menu. Available modes are
the mesh once. Using the jiggle mode
the jiggling process is repeated until the minimum triangle quality
stops increasing or until the iteration limit is reached. The same
applies for the
optimize mean option, but it tries
to increase the mean triangle quality.
Number of jiggle iterations: Iteration
limit for the
optimize minimum and
mean modes. Default: 20.
For the mesh refinement algorithm

method can be
The default refinement method is
regular, which results in a uniform

To initialize a triangular mesh, select Initialize Mesh from the Mesh menu or click the button. To refine a mesh, select Refine Mesh from the Mesh menu or click the button.
