General Axisymmetric

Creates a three-dimensional mesh in the circumferential direction on a surface body model that is based on specified nodal planes and an axis. This feature supports edge and vertex scoping only. From these surface model edges and vertices, you can generate three-dimensional node-based Named Selections that you can then use as scoping items for other simulation options such as loading conditions and/or results.

This feature uses the Mechanical APDL elements SOLID272 and SOLID273.

Object Properties

The Details Pane properties for this object include the following.

Category Properties/Options/Descriptions

Category	Properties/Options/Descriptions
Scope	Scoping Method: Read-only field. Geometry Selection is the only supported option. Geometry: Specify the geometry using geometry selections. You can specify any planar surface body. Only Body scoping is supported.
Definition	Nodal Planes: Specify the desired number of nodal planes. Your entry defines the number of planes around the axis and on which nodes should be generated. The entry for this property can be either `1` or `3` through `12`. A Nodal Planes entry of 2 is not supported. Coordinate System: As needed, specify a coordinate system. The default setting is the Global Coordinate System. Axis: Specify the axis about which the axisymmetric mesh is generated. Options include X Axis, Y Axis, and Z Axis. This setting must lie along the body, it cannot intersect the body, and it must be specified on the same plane as the selected surface body. Suppressed
Graphics	Nodal Planes Visible: Select the range of planes for which the mesh or results can be displayed. The maximum number of planes that can be displayed is defined by the Nodal Planes property. Options include All (default) and Range. Changing the setting to Range specifies a desired range, such as 1-6 or 6-12, of the number of planes that you want to display for the mesh and results objects. When you select Range, the following properties display: Start Plane: Specify the plane number for where you want the display to start. The default value is 1. End Plane: Specify the plane number where the display ends. The default setting is Last. Entering a value of zero is the same as specifying Last.

Graphics

Nodal Planes Visible: Select the range of planes for which the mesh or results can be displayed. The maximum number of planes that can be displayed is defined by the Nodal Planes property. Options include All (default) and Range. Changing the setting to Range specifies a desired range, such as 1-6 or 6-12, of the number of planes that you want to display for the mesh and results objects.
