Hi Nithish,

This error shows that the dependent DOF has been selected in the independent DOF too. Delete the dependent DOF from the independent DOF list and run the analysis.

UseTools-> check elems->1-D rigid loops and dependency (check including independent nodes). This will help to figure the 1-D elements that share a node (dependent or independent)are considered to fail the check.
