Mapdl.arotat(nl1='', nl2='', nl3='', nl4='', nl5='', nl6='', pax1='', pax2='', arc='', nseg='', **kwargs)

Generates cylindrical areas by rotating a line pattern about an axis.

Mechanical APDL Command: AROTAT

Parameters:

nl1str

List of lines in the pattern to be rotated (6 maximum if using keyboard entry of NL1 to NL6 ). The lines must lie in the plane of the axis of rotation. If NL1 = P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI). If NL1 = ALL, all selected lines will define the pattern to be rotated. A component name may also be substituted for NL1.

nl2str

List of lines in the pattern to be rotated (6 maximum if using keyboard entry of NL1 to NL6 ). The lines must lie in the plane of the axis of rotation. If NL1 = P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI). If NL1 = ALL, all selected lines will define the pattern to be rotated. A component name may also be substituted for NL1.

nl3str

List of lines in the pattern to be rotated (6 maximum if using keyboard entry of NL1 to NL6 ). The lines must lie in the plane of the axis of rotation. If NL1 = P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI). If NL1 = ALL, all selected lines will define the pattern to be rotated. A component name may also be substituted for NL1.

nl4str

List of lines in the pattern to be rotated (6 maximum if using keyboard entry of NL1 to NL6 ). The lines must lie in the plane of the axis of rotation. If NL1 = P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI). If NL1 = ALL, all selected lines will define the pattern to be rotated. A component name may also be substituted for NL1.

nl5str

List of lines in the pattern to be rotated (6 maximum if using keyboard entry of NL1 to NL6 ). The lines must lie in the plane of the axis of rotation. If NL1 = P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI). If NL1 = ALL, all selected lines will define the pattern to be rotated. A component name may also be substituted for NL1.

nl6str

List of lines in the pattern to be rotated (6 maximum if using keyboard entry of NL1 to NL6 ). The lines must lie in the plane of the axis of rotation. If NL1 = P, graphical picking is enabled and all remaining arguments are ignored (valid only in the GUI). If NL1 = ALL, all selected lines will define the pattern to be rotated. A component name may also be substituted for NL1.

pax1str

Keypoints defining the axis about which the line pattern is to be rotated.

pax2str

Keypoints defining the axis about which the line pattern is to be rotated.

arcstr

Arc length (in degrees). Positive follows right-hand rule about PAX1 - PAX2 vector. Defaults to 360°.

nsegstr

Number of areas (8 maximum) around circumference. Defaults to minimum number required for 90° -maximum arcs, that is, 4 for 360°, 3 for 270°, etc.

Notes

Generates cylindrical areas (and their corresponding keypoints and lines) by rotating a line pattern (and its associated keypoint pattern) about an axis. Keypoint patterns are generated at regular angular locations, based on a maximum spacing of 90°. Line patterns are generated at the keypoint patterns. Arc lines are also generated to connect the keypoints circumferentially. Keypoint, line, and area numbers are automatically assigned, beginning with the lowest available values ( numstr ). Adjacent lines use a common keypoint. Adjacent areas use a common line.
