Vertex
Use Vertex () to mesh points in 1D, 2D, and 3D. The operation is useful when meshing isolated vertices, as shown in Figure 8-113.
Figure 8-113: Meshing the isolated point (blue) using the Vertex operation. For this ray acoustics simulation, only the boundaries and the isolated vertex need a mesh.
Isolated vertices are automatically meshed if a Free Tetrahedral, Free Triangular, Free Quad, or Edge operation is built with Geometric entity level set to Remaining or Entire Geometry. For the Mapped operation, isolated vertices are automatically meshed if Geometric entity level is set to Remaining.
To add a Vertex () node, select one or several points in the Graphics, then choose one of the following:
•
Right-click in the Graphics window, and select Vertex () from The Graphics Context Menu.
•
In The Mesh Toolbar, choose Vertex from the More Generators () menu (3D or 2D components) or click Vertex () (1D components).
•
Right-click the Mesh node and choose Vertex () (under More Generators in 3D).
Then enter the properties using the following sections:
Entity Selection
To define the points where you want a create a mesh, first choose the level of the geometric entities from the Geometric entity level list:
•
Choose Entire geometry to generate a vertex mesh for the entire geometry.
•
Choose Remaining to specify a vertex mesh for the remaining, unmeshed vertices.
•
Choose Point (3D and 2D) or Boundary (1D) to specify the points for which you want to create a mesh. Choose Manual in the Selection list to select the points in the Graphics window, choose a named selection to refer to a previously defined selection, or choose All points (3D and 2D) or All boundaries (1D) to select all points.
