Auto-mesh Planar Area

 

 

 

Automatically generate a mesh by specifying an area.

 

 

 

From the Main Menu select Node/Element > Mesh > Auto-mesh Planar Area.

 

 

 

Mesher

 

Method: Specify an area for the mesh. There are three ways of specifying an area: Nodes, Line Elements, Planar Elements

 

Nodes : Selected nodes are displayed according to the order of selection. The selected nodes should exist on the same plane to create a mesh.

 

Line Elements : Selected line elements are displayed in sequential order. The selected line elements should exist on the same plane to create a mesh.

 

Planar Elements : Selected planar elements are displayed in sequential order. The planar elements need not be on the same plane to create a mesh.

 

 

Type

 

Quadrilateral : Generate a mesh using quadrilateral elements.

 

Quad+Triangle : Generate a mesh using quadrilateral elements and triangular elements.

 

Triangle : Generate a mesh using triangular elements.

 

 

Mesh Inner Domain

 

If this option is selected and there is an inner domain within the mesh area, a mesh is generated in the domain too.

 

 

 

Include Interior Nodes

 

If this option is selected and there is a node within the area to be meshed, a mesh is generated considering the node. The interior nodes can be automatically detected or specified by the user.

 

 

 

Include Interior Lines

 

If this option is selected and there is a line within the area to be meshed, a mesh is generated considering the line. The interior lines can be automatically detected or specified by the user and can be from line elements, planar elements or solid elements.

 

 

 

Include Boundary Connectivity

 

Consider the mesh connectivity of adjacent meshes.

 

Mesh Size

 

Define the size of the mesh elements. The size can be defined by a length or by the number of divisions.

 

Length : Define the side length of the mesh elements.

 

Division : Define the number of divisions for the reference elements comprising the area to be meshed.

 

 

Property

 

Element Type

 

Select the element type of the planar mesh elements to be created. There are four element types available: Plate, Plane Stress, Plane Strain and Axisymmetric. The  button to the right becomes active when the element type is Plate or Plane Stress. Click the button to define the Element Sub Type.

 

 

Material : Enter the material property of the planar mesh elements to be created. Click to the right to invoke the Material dialog box.

 

Thickness : Enter the thickness data of the planar mesh elements to be created. Click  to the right to invoke the Thickness dialog box.

 

 

Domain

 

Name : Define the name of Domain.

 

 

Delete Boundary Line Elem.

 

If this option is selected, the line elements on the periphery of the mesh area are deleted after the mesh is generated.

 

 

 

 

Subdivide Boundary Line Elem.

 

This option can be used when 'Delete Boundary Line Elem.' is not selected. If this option is selected, the line elements on the periphery of the mesh area are divided according to the mesh size. The divided line elements are registered as a Member and it can be checked in the Member Assignment dialog.
