Run Failed at Pass 1 - Nonlinear static analysis with thermal drift and contacts

I am using Creo Simulate Release 7.0 and Datecode7.0.10.0 SUBJECT: Creo Simulate: Nonlinear Static Analysis Fails at Pass 1 (Thermal Drift & Contacts) 1. SETUP SUMMARY: - Objective: Evaluate deformation/stress under thermal drift. - Model: 2-body assembly in Creo Simulate Structure Mode. - Constraints: Fixed displacement on support frame. - Loads: Thermal drift (20°C to 40°C). - Contacts: Surface-to-Surface with finite friction (Static/Dynamic = 0.74). - Fasteners: 2x screw-type (Ø4 mm, X5CrNi18-10, 6.8 head/nut) with 5949.6 N preload. - Mesh (AutoGEM): Default settings (no extra controls). - Analysis: Nonlinear static, Large Deformations, Contacts, Detailed Stresses at Contact Interfaces. Single-Pass Adaptive (Medium Accuracy). 2. ISSUE: Nonlinear static execution stops immediately after Pass 1 with status "Run Failed". 3. SUPPORT REQUEST: - What is the recommended procedure in Creo Simulate for defining frictional contacts to prevent nonlinear iteration failure? - If replacing ideal fasteners with 3D-modeled solid screws, what is the correct workflow for handling frictional/non-frictional contact interfaces? Here are the errors that I faced The nonlinear iteration did not converge. Please review your loads and boundary conditions. Run completed with fatal error.
