| | 1105 | These two joints have been changed in a slightly not backward compatible |
| | 1106 | way, in order that the usage in the Assemblies.JointXYZ joints results in |
| | 1107 | balanced models (<b>no conversion is provided for this change since the |
| | 1108 | user should not have used these joints and the conversion would be too |
| | 1109 | complicated</b>): |
| | 1110 | In releases before version 3.0 of the Modelica Standard Library, |
| | 1111 | it was possible to activate the torque/force projection equation |
| | 1112 | (= cut-torque/-force projected to the rotation/translation |
| | 1113 | axis must be identical to |
| | 1114 | the drive torque/force of flange axis) via parameter <b>axisTorqueBalance</b>. |
| | 1115 | This is no longer possible, since otherwise this model would not be |
| | 1116 | \"balanced\" (= same number of unknowns as equations). Instead, when |
| | 1117 | using this model in version 3.0 and later versions, the torque/force |
| | 1118 | projection equation must be provided in the Advanced menu of joints |
| | 1119 | Joints.SphericalSpherical and Joints.UniversalSpherical |
| | 1120 | via the new parameter \"constraintResidue\".</td> </tr> |
