The Transformation handler tries to remove (transform) the equation for the constrained DOF making it a function of the retained DOF. When this constrained equation (eliminated) is to be used as a retained equation in the second MP constraint, it won't be found, thus the second constraint wi...
Improved : Body constraint (equalDOF) condition is split into two conditions, for master and slave nodes, respectively. Body constraints are now defined on the geometry model Improved : Pushover Analysis. In case of analysis divergence,substeppingand alternative convergence criteria are automatically ap...

constraint 命令用于指定如何处理模型中的约束。模型中的约束分为两种,分别是单点(Single Point)约束 SP_Constratint 和多点(Multiple Point)约束 MP_Constraint 。其中:单点约束,是指对结点本身的约束,如 fix 代表节点的自由度约束,即支座。此外还有外加位移等。多点...
