2023R1 Contact & Nonlinear Solver Heuristics Enhancements • Support contact for 2D axisymmetric elements with torsion ROTY • DMP contact performance improvement: ‐ Distribute underlying elements of target surface into different domains for node-surface contact CONYA175 ‐ Concurrent contact trimming and pair splitting to avoid external element numbering overflow • Contact options for shells – BIW workflows ‐ Double sided target surface ‐ Limited CEs for rigid constraint under small deflection • Contact result, convergence history tracking in PyMAPDL • Enhance NLHIST stop criteria: tracking result variables to terminate solution besides contact results • Improve robustness for transient dynamics: initialized acceleration, backward-Euler integration scheme as default for 1st order equations. • Improve accuracy for New-Raphson iterations: refine force/displacement convergence tolerances.
