help with adding MPC in keyword editor
(OP)
I am trying to use the Quadratic multipoint contraint in order to reduce the amount of elements in my model. So I am trying to go from a fine to a course mesh, but I am unsure of where to add this MPC constraint within the keyword editor. In the ABAQUS/Standard tutorial, for the cargo crane example, they added the MPC within the assembly option block, right before the *end assembly keyword line. I try to do that also using the nodes assigned from the once I meshed my assembly, but I get errors saying surface and element sets are unknown and dont exist even though in the lines above where I entered the MPCs, the element sets, instances, and surfaces are defined. Anyone have an idea what I am doing wrong. Thank you

Alternatively, like Yoman228 said, you may get just as good a result using tied surfaces instead. These are supported in the Interaction module in CAE.

Also, the keyword editor in 6.7 doesn't appear to work now and you have to edit the .inp file manually. Do they check software before the issue it or wait for the customer to find the bugs?

How can i retain the MPC definitions during the analysis?
Can someone please look at my input file and help me out, you'll realize that when you load the input file, the composite layup disappears, but the beam section definition remains.

So I added my MPC to the input file and saved it as a new name. Then imported the model in ABAQUS. It gives me a warning message:
WARNING: The following keywords/parameters are not yet supported by the input file reader:
---------------------------------------------------------------------------------
*MPC
So I guess it turns out v6.7 might not support MPC. Corus, have you made it work before?
