TO define a node set for the right side, say RIGHT. make a reference node,(NSET=REF_RIGHT) which is not involved in the model. then, use:<br />*KINEMATIC COUPLING, REF NODE= REF_RIGHT.<br />RIGHT, 1<br /><br />reference: 20.2.3-1:KINEMATIC COUPLING CONSTRAINTS ( V6.5)<br />Typical applications:
Typical applications:<br /> The kinematic coupling constraints are useful in cases where a large number of nodes (the “coupling” nodes) are constrained to the rigid body motion of a single node and the degrees of freedom that participate in the constraint are selected individually in a local coordinate system. In many such cases MPCs either are not available or would have to be prescribed individually for each constrained node. A typical example is shown in Figure 28.2.3–1, where a kinematic coupling constraint is used to prescribe a twisting motion to a model without constraining radial motions. In other applications the kinematic coupling constraint can be used to provide coupling between continuum and structural elements.
如果我设置两个,则出现以下的错误信息:1 nodes are missing degree of freedoms. The MPC/Equation/kinematic coupling constraints can not be formed. The nodes have been identified in node set ErrNodeMissingDofConstrDef.<br /><br />如果我只设一个,不能达到我的目的,得到的位移分布图如下:<br />1方向：
