Dependency Panel
Use the Dependency panel to find nodes that have their degrees of freedom removed by a constraint or MPC (multiple point constraint) more than once. By identifying and correcting such dependencies prior to solving, solution errors can be avoided.

Note: Nodes that have multiple constraints or MPCs are
placed on the temporary node mark. However, nodes with multiple constraints or
MPC's can cause solution errors in many solvers. Every situation should be
evaluated and corrected accordingly. In the case of rigid elements, often
swapping the independent and dependent nodes of the elements, or moving the
constraints to the independent nodes, will correct the problem.
