error1 The solver engine was unable to converge on a solution for the nonlinear problem as constrained. Please see the Troubleshooting section of the Help System for more information.
warning2 At least one body has been found to have only 1 element in at least 2 directions along with reduced integration. This situation can lead to invalid results. Consider changing to full integration element control or meshing with more elements. Refer to Troubleshooting in the Help System for more details.
warning3 The unconverged solution (identified as Substep 999999) is output for analysis debug purposes. Results at this time should not be used for any other purpose.
warning4 One or more contact regions may not be in initial contact. Check results carefully. Refer to Troubleshooting in the Help System for more details.
warning5 Contact status has experienced an abrupt change. Check results carefully for possible contact separation.
