The AMOM function returns the component comp of the total Angular Momentum of all Bodies with mass in a model. This includes PART (PLANAR and 3D), FE_PART (2D and 3D), FLEX_BODY, and POINT_MASS. The computed Momentum is returned in Global coordinates. The Angular Momentum is computed about a reference location, which is specified by rm. rm is optional. If it is omitted, the Angular Momentum is computed about the Global origin.
Format
AMOM (comp, rm)
Arguments
comp | An integer value that specifies the component of the total Angular Momentum. ■1 - x-component of the total Angular Momentum ■2 - y-component of the total Angular Momentum ■3 - z-component of the total Angular Momentum |
rm | A marker ID which references the location for computing Angular Momentum. |
Examples
REQUEST/1
, F2= AMOM(1)/
, F3= AMOM(2)/
, F4= AMOM(3)
This REQUEST statement outputs the x-, y- and z-components of the total Angular Momentum of all Bodies with mass about the Global origin. The Momentum is in Global coordinates.
REQUEST/1
, F2= AMOM(1,101)/
, F3= AMOM(2,101)/
, F4= AMOM(3,101)
This REQUEST statement outputs the x-, y- and z-components of the total Angular Momentum of all Bodies with mass about the Global location of MARKER/101. The Momentum is in Global coordinates.
Caution: | The AMOM function should only be used in REQUEST and SENSOR statements. |
