Coupled-Field Enhancements • Usability: Coupled-field elements with structural DOFs now output Euler angles with large deflection to allow results post-processing in the global coordinate system. • Robustness: Stiffness matrix calculation has been enhanced for coupled-field elements with temperature dependent material properties to improve convergence of the nonlinear solution. • New Capability: The enhanced strain formulation is now available for the piezoelectric analysis with lower order coupled-field elements PLANE222 and SOLID225. 113 A cantilever beam under combined varying structural and voltage load. Significant accuracy improvement with lower order SOLID225 elements
