MCOG()

moment about of the center of gravity for a given MOVE-flag

[ ... MCOG(i,$MOVEFlag$, OPTIONAL: iWhat ) ... ]

i = 1,2,3 yields the x-, y-, z-component of the rotational speed $ \omega$ of the center of gravity for the given $MOVEFlag$, respectively.
$MOVEFlag$ is directly associated to all boundary elements carrying this MOVE-flag.
IWhat (DEFAULT=0) : 0 => sum of EXTERNAL moments around the xCOG() (given by %MOVE_Rigid% and/or RIGIDBODY_ExternalForces) + moments due to pressure/tension forces acting om body 1 => sum of moments due to pressure/tension 2 => sum moments due to all EXTERNAL forces 3 => sum of moments due to pressure and tension forces (same as 1, but try to keep consistency with FCOG() 4 => sum of all moments due to intersection of the rigid body with walls or other rigid bodies 5 => sum of all moments due to joints, acting on the rigid body
