Hello, I am running a static structural simulation to identify some mechanical characteristics of coronary artery stent expands by balloon inflation. When I execute solve, nothing displays in the solver output nor force convergence graph. Also the following error occurred whenever I click on the solution to solve even after I do changes in the contact or time substeps:

1) Error: 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 matertial properties, an under constrained model, or contact related issues. Check results carefully.

2) The result file cannot be opened.

3) current result file may not contain requested result data. Please clear the solution and solve again.

4) The Restart Analysis failed as all required files for Restart were not found. Check the Solver Output on the Solution Information object for possible causes.

Could someone please help?

The simulated model is attached below:
