*tie 和MPC命令一样吗？

连接梁单元和实体单元时（无公共节点），有人提议用*tie, 也有人用MPC，这两种方法有什么区别啊？

mpc？

Multipoint Constraint Elements啊，我记得用约束方程是可以的。这个就不知道了

In addition to the methods discussed here, you can use the internal multipoint constraint (MPC) feature of certain contact elements (CONTA171, CONTA172, CONTA173, CONTA174, and CONTA175) to model contact assemblies and kinematic constraints. By this method, the program builds MPC equations internally based on the contact kinematics. See Chapter 7: "Multipoint Constraints and Assemblies" in the ANSYS Contact Technology Guide for more information on how to use this feature.
看来mpc和约束方程效果是一样的哦，都可以。
