PARAMETERS
NameTypeDefault ValueDescription
animationBooleantrue= true, if animation shall be enabled
showMassBooleantrue= true, if mass shall be shown (provided animation = true and m > 0)
computeRodLengthBooleanfalse= true, if rodLength shall be computed during initialization (see info)
rodLengthLengthDistance between the origins of frame_a and frame_b (if computeRodLength=true, guess value)
mMass0Mass of rod (= point mass located in middle of rod)
sphereDiameterDiameterworld.defaultJointLengthDiameter of spheres respresenting the spherical joints
rodDiameterDiametersphereDiameter/Types.Defaults.JointRodDiameterFractionDiameter of rod connecting the two spherical joint
massDiameterDiametersphereDiameterDiameter of sphere representing the mass point
kinematicConstraintBooleantrue= false, if no constraint shall be defined, due to analytically solving a kinematic loop ("false" should not be used by user, but only by MultiBody.Joints.Assemblies joints)
checkTotalPowerBooleanfalse= true, if total power flowing into this component shall be determined (must be zero)
