遇到以下错误是什么原因

1. Whenever a translation (rotation) dof at a node is constrained by a kinematic coupling definition the translation (rotation) dofs for that node cannot be included in any other constraint including mpcs, rigid bodies, etc.

2. For contact pair (assembly__pickedsurf469-assembly__pickedsurf468), adjusted nodes with very small adjustments were not printed. Specify *preprint,contact=yes for complete printout.

3. The ratio of the maximum incremental adjustment to the average characteristic length is 1.64259e-02 at node 46 instance beam-1 on the surface pair (assembly__pickedsurf475,assembly__pickedsurf474).

4. Not all the nodes that have been adjusted were printed. Specify *preprint,contact=yes for complete printout.

5. Boundary conditions are specified on inactive dof of 64 nodes. The nodes have been identified in node set WarnNodeBCInactiveDof.

6. The strain increment has exceeded fifty times the strain to cause first yield at 1728 points
