ansys.mapdl.core.Mapdl.cone

Mapdl.cone(rbot='', rtop='', z1='', z2='', theta1='', theta2='', **kwargs)

Creates a conical volume centered about the working plane origin.

Mechanical APDL Command: CONE

Parameters:

rbotstr

Radii of the bottom and top faces of the cone. A value of zero or blank for either RBOT or RTOP defines a degenerate face at the center axis (that is, the vertex of the cone). The same value for both RBOT and RTOP defines a cylinder instead of a cone.

rtopstr

Radii of the bottom and top faces of the cone. A value of zero or blank for either RBOT or RTOP defines a degenerate face at the center axis (that is, the vertex of the cone). The same value for both RBOT and RTOP defines a cylinder instead of a cone.

z1str

Working plane Z coordinates of the cone. The smaller value is always associated with the bottom face.

z2str

Working plane Z coordinates of the cone. The smaller value is always associated with the bottom face.

theta1str

Starting and ending angles (either order) of the cone. Used for creating a conical 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° and the ending angle defaults to 360°. See the Modeling and Meshing Guide for an illustration.

theta2str

Starting and ending angles (either order) of the cone. Used for creating a conical 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° and the ending angle defaults to 360°. See the Modeling and Meshing Guide for an illustration.

Returns:

int

Volume number of the cone.

Notes

Defines a solid conical volume centered about the working plane origin. The non-degenerate face (top or bottom) is parallel to the working plane but not necessarily coplanar with (that is, “on”) the working plane. The cone must have a spatial volume greater than zero. (that is, this volume primitive command cannot be used to create a degenerate volume as a means of creating an area.) For a cone of 360°, 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 con4 command for an alternate way to create cones.

Examples

Create a quarter cone with a bottom radius of 3, top radius of 1 and a height of 10 centered at (0, 0).
