FCOG()

integrated forces acting on the center of gravity for a given MOVE-flag

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

i = 1,2,3 yields the x-, y-, z-component of the forces for the given $MOVEFlag$ , respectively, If the body is %MOVE_rigid% i = 4 yields the complete force of the body, if the body is %MOVE_MassSpringDashpot%
$MOVEFlag$ is directly associated to all boundary elements carrying this MOVE-flag.
IWhat (DEFAULT=0) : if body is of type %MOVE_rigid%: 0 => sum of EXTERNAL forces (given by %MOVE_Rigid% and/or RIGIDBODY_ExternalForces) + pressure/tension forces acting om body + gravity forces 1 => sum of pressure/tension forces + gravity forces 2 => simply sum of EXTERNAL forces 3 => pressure and tension forces 4 => sum of all forces due to intersection of the rigid body with walls or other rigid bodies 5 => sum of all forces due to joints, acting on the rigid body if body is of type %MOVE_MassSpringDashpot%: 0 => complete force of the system 1 => precompression force 2 => force due to spring compression 3 => force due to the damper
