OVERCONSTRAINT CHECKS:
An overconstraint was detected at node 98 INSTANCE SPLINE-2-1. There are multiple constraints
applied directly or chained constraints that are applied indirectly at this node.
A list of nodes and chained constraints between these nodes that most likely lead
to the detected overconstraint can be printed out to the message file by including
*constraint controls, print=yes in the input file.
