Hi everyone,
I just started to use the Abaqus FE program and I would like to ask some help. I would like to determine the elastic properties of a composite material therefore I designed an representative element but I need to constraint the nodes of each surface to achieve uniform deformation at each nodes on the surface. I tried the multiple point constraints but I alvalys got an error message saying that:
80 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.
I am not even sure whethe I am using the correct command to constraint the nodes.
If anyone would help me that would be wonderfull,
Thanks
