Workbench stuck from 5-10% in preparing/solving mathematical model

      From the shared snapshot it appears that 84% of memory is in use. Could you please share the memory specification of the system? Do you see an error in solve.out file if generated?
      Is this issue specific to this model or to any other simple model with very few elements?
      Thanks

      I've attached an image of the memory, please let me know if that is what you are looking for.
      I can't see a solve.out file in the project files.
      I believe the issue is model specific, it failed after 47hrs of running. I have attached a screenshot of the errors I received after it failed. I am fairly confident that all of the contact conditions are ok, so it may lie in the analysis settings.
      I will try to debug the solution with the advice from the error warnings above. But I would appreciate any insight or guidance!
      For context, I am radially expanding a coronary stent using a balloon. The displacement is from 3mm to 6mm. I have attached a photo of the geometry and the analysis settings too.

      It seems you have 8GB ram in your workstation. And if you start a simulation with large deformation, it obviously take time depends on your non linearity. (Material, geometry, contact)
      In your case,
      1) Try restarting your workstation before start the simulation.
      2) Do clear generated data before start the simulation.
      3) Check your mesh quality.(aspect ratio)
      4) Check contact settings with contact tool.
