***WARNING: SOLVER PROBLEM. ZERO PIVOT WHEN PROCESSING A (TIED) CONTACT
CONSTRAINT D.O.F. 1 FOR SLAVE NODE 147300 INSTANCE PART-1-1. THIS
MAY BE DUE TO THE UNIT USED FOR THE DISPLACEMENT DIFFERS BY MORE
THAN 10 ORDER OF MAGNITUDE THAN THE UNIT USED FOR THE MATERIAL
STIFFNESS. IF THIS IS THE CASE, PLEASE USE A DIFFERENT UNIT
SYSTEM.
OVERCONSTRAINT CHECKS:
An overconstraint was detected at one of the Lagrange multipliers associated
with contact slave node 147300 INSTANCE PART-1-1. There are multiple constraints applied directly
or chained constraints that are applied indirectly to 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.
***WARNING: Solver problem. Zero pivot when processing D.O.F. 1 of 16 nodes.
The nodes have been identified in node set
