naxis

Mapdl.naxis(action='', val='', **kwargs)

Generates nodes for general axisymmetric element sections.

APDL Command: NAXIS

Parameters
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 3-D element plot to appear more like the actual 3-D 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.
