To generate a finite element mesh by selecting corner
nodes, use the following procedure.
You must have three or more existing nodes that lie in a plane in your
analytical model.
This procedure is
used to immediately generate a mesh within a selection of vertices. If you
would like to investigate changing parameters prior to generating a mesh or to
add openings with the mesh, then you may want to use the procedure a
parametric mesh
model instead.
On the
Geometry ribbon tab, select the
Generate Mesh > Create
Mesh tool in the
Plate group.
The mouse pointer changes to a mesh cursor.
Click the nodes that will form the vertices of the mesh area, in
either a clockwise or counter clockwise order.
Notes:
The order of the
nodes should be in either a clockwise or counterclockwise direction.
The nodes must for a
polygonal area (i.e., they edges cannot cross).
The nodes must lie
in the same plane.
When you have select the corner nodes, either:
select the first
node again
press
Esc
The
Choose Meshing Type dialog opens.
Select the type of meshing to use and then click
OK.
Polygonal Meshing
Only triangular elements will be created
Quadrilateral Meshing
This will create principally four sided elements, but where
the geometry dictates, some places may require triangular elements.
The
Define Mesh Region dialog opens.
Review the mesh vertices:
Click the Add New Row tool to add a new vertex.
Click the Delete Row tool to remove the currently selected
row.
Select the Holes tree entry to add openings to the mesh.
