Whenever a translation (rotation) dof at a node is constrained by a kinematic coupling definition the translation (rotation) dofs for that node cannot be included in any other constraint including mpcs, rigid bodies, etc.

MPCS (EXTERNAL or INTERNAL, including those generated from rigid body definitions), KINEMATIC COUPLINGS, AND/OR EQUATIONS WILL ACTIVATE ADDITIonAL DEGREES OF FREEDOM

11 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

汉语大概意思如下：

每当节点的平移（旋转）自由度受到运动耦合定义的约束时，该节点的平移（旋转）DOF不能被包括在包括MPC、刚体等的任何其它约束中。

MPC（外部或内部，包括刚体定义产生的）、运动联轴器和/或方程将激活额外的自由度。

11个元素是扭曲的。要么等参角是超出建议的极限，要么三角形或四面体质量测量是坏的。元素在元素集WalnEnter变形中被识别。
