Problem about Deformation of a Biomedical Stent with Simulation

Hello guys, I encountered a problem when conducting the mechanical simulation of a bracket and would like to seek advice from everyone. In the reference case, due to the symmetry of the bracket, only a 1/24 model was established for calculation; however, my own bracket structure is not completely symmetrical, so I hope to directly establish and calculate the entire bracket model. But when using the complete model, an error occurs during the solution process: "The iteration for finding the elastic-plastic strain variable did not converge." I would like to ask what usually causes this situation? Is it a problem with material parameters, boundary conditions, contact settings, or mesh/solver settings? If you have similar experience, please share some troubleshooting ideas. Thank you very much.
