@peteroznewmannDear peternI tried to run the model but I still have error and warning messages if you can help me to solve them I have attached my model if you can check it.nnerror:n#1 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.nwarning:n#1 The solution failed to solve completely at all time points. Restart points are available to continue the analysis. n#2 Although the solution failed to solve completely at all time points, partial results at some points have been able to be solved. Refer to Troubleshooting in the Help System for more details.n#3 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.n#4 Solver pivot warnings or errors have been encountered during the solution. This is usually a result of an ill conditioned matrix possibly due to unreasonable material properties, an under constrained model, or contact related issues. Check results carefully.n#5 Contact status has experienced an abrupt change. Check results carefully for possible contact separation.n#6 One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions or other contact or symmetry regions. This may reduce solution accuracy. Tip: You may graphically display FE Connections from the Solution Information Object for non-cyclic analysis. Refer to Troubleshooting in the Help System for more details.n#7 Two or more remote boundary conditions are sharing a common face, edge, or vertex.  This behavior can cause solver overconstraint and is not recommended, please check results carefully. You may select the offending object and/or geometry via RMB on this warning in the Messages window.n#8 An all-quad-free face mesh type was chosen, but some triangles were created during meshing.n#9 One or more objects may have lost some scoping attachments during the geometry update. You can identify these tree objects by filtering the tree using the Scoping option set to Partial.nn n
