MPC constraint

[NEROOO]

Hi,

I'm trying to use the user-defined MPC, and according to the manual saying that for keyword *MPC:

*MPC，user, mode=node
1, nset1, nset2, nset3, nset4,...

however, when I applied the interactive MPC constraint, the generated .inp file writes:

*MPC, user, mode=node
1, matserset, slaveset

which only allowed two sets, master and salve set, to be defined.

How could I apply multiple node sets and make them in order? I'm using version 2018.


Thanks a lot!

In case of a larger number of constraints it’s often easier to define them manually by editing the input files (just create proper sets before doing that) instead of crrating separate constraints in Abaqus/CAE.
