cylind

Mapdl.cylind(rad1='', rad2='', z1='', z2='', theta1='', theta2='', **kwargs)

Create a cylindrical volume centered about the working plane origin.

APDL Command: CYLIND

Defines a cylindrical volume centered about the working plane origin. The top and bottom faces are parallel to the working plane but neither face need be coplanar with (i.e., “on”) the working plane. The cylinder must have a spatial volume greater than zero. (i.e., this volume primitive command cannot be used to create a degenerate volume as a means of creating an area.)

For a solid cylinder of 360°, the top and bottom faces will be circular (each area defined with four lines), and they will be connected with two areas (each spanning 180°.) See the CYL4 and CYL5 commands for alternate ways to create cylinders.

Parameters:

rad1, rad2

Inner and outer radii (either order) of the cylinder. A value of zero or blank for either RAD1 or RAD2, or the same value for both RAD1 and RAD2, defines a solid cylinder.

z1, z2

Working plane Z coordinates of the cylinder. If either Z1 or Z2 is zero, one of the faces of the cylinder will be coplanar with the working plane.

theta1, theta2

Starting and ending angles (either order) of the cylinder. Used for creating a cylindrical sector. The sector begins at the algebraically smaller angle, extends in a positive angular direction, and ends at the larger angle. The starting angle defaults to 0.0° and the ending angle defaults to 360.0°. See the Modeling and Meshing Guide for an illustration.

Returns:

int

Volume number of the cylinder.

Return type:

int

Examples

Create a hollow cylinder with an inner radius of 0.9 and an outer radius of 1.0 with a height of 5

>>> vnum = mapdl.cylind(0.9, 1, z1=0, z2=5)
>>> vnum
