Mapdl.spoint(node='', x='', y='', z='', inertiakey='', **kwargs)#

Defines a point for force/moment summations or inertia calculation

Mechanical APDL Command: SPOINT

Parameters:

nodestr

Node number of the desired point. If zero, use X, Y, Z to describe point.

xstr

Global Cartesian coordinates of the desired summation point. Used if NODE is 0. Defaults to (0,0,0).

ystr

Global Cartesian coordinates of the desired summation point. Used if NODE is 0. Defaults to (0,0,0).

zstr

Global Cartesian coordinates of the desired summation point. Used if NODE is 0. Defaults to (0,0,0).

inertiakeystr

Inertia key:

• OFF - Point or node is used for the force/moment summations (default).

• ON - Point or node is used for the calculation of total inertia.

Notes

By default ( InertiaKey = OFF), defines a point (any point other than the origin) about which the tabular moment summations are computed. If force summations are desired in other than the global Cartesian directions, a node number must be specified on the NODE field, and the desired coordinate system must be activated with rsys. The command must be issued in the post1 module.

When the inertia key is activated ( InertiaKey = ON), the total inertia printed in the precise mass summary is calculated with respect to the point or node in the global Cartesian system. In this case, the command must be issued during the first load step in the slashsolu module.
