NAXIS
NAXIS, Action
, Val
Generates nodes for general axisymmetric element sections.
Action
Specifies one of the following command behaviors:
GEN
—
Generates nodes around the axis of an axisymmetric section (default).
CLEAR
—
Clears all nodes around the axis of an axisymmetric section.
EFACET
—
Specifies the number of facets per edge between nodal planes and integration planes in the circumferential direction to display using PowerGraphics. This option is only valid with /ESHAPE,1 and RSYS,SOLU commands.
Val
Tolerance value or number of facets per edge:
TOLER
—
When
Action
= GEN, the tolerance to use for merging the generated nodes around the axis.NUM
—
When
Action
= EFACET, the number of facets per element edge for element plots:AUTO
—
Use program-chosen facets per edge (default).
1
—
Use 1 facet per edge (default for elements with 9, 10, 11, or 12 nodal planes). Shows nodal and integration planes only.
2
—
Use 2 facets per edge (default for elements with 5, 6, 7, or 8 nodal planes, and maximum for elements with 9, 10, 11, or 12 nodal planes).
3
—
Use 3 facets per edge (default for elements with 3 or 4 nodal planes, and maximum for elements with 6, 7, or 8 nodal planes).
4
—
Use 4 facets per edge (maximum for elements with 5 nodal planes).
5
—
Use 5 facets per edge (maximum for elements with 4 nodal planes).
6
—
Use 6 facets per edge (maximum for elements with 3 nodal planes).
Notes
The NAXIS command generates or clears the nodes for general axisymmetric element sections. The command applies to elements SURF159, SOLID272, and SOLID273.
The generate option (Action
= GEN)
operates automatically on any current-technology axisymmetric element.
Any nodes within the tolerance value (TOLER
) of the axis are merged into a single node. The default tolerance
is 1.0e-4.
If you want to change the number of nodes, use the clear option
(Action
= CLEAR) before regenerating the
nodes.
To cause the 3D element plot to appear more like the actual
3D model, use NAXIS,EFACET,NUM
, where NUM
> 1. In this case, the coordinate
system specified for displaying element and nodal results (RSYS) must
be solution (RSYS,SOLU); otherwise, Ansys resets NUM
to 1.
