WebMay 10, 2024 · In step 4 we mentioned bisection. At what point the model decides to “bisect” is a function of the number of equilibrium iterations defined for that Time Step. Equilibrium Iterations refers to the maximum number of iterations the model will attempt to reach a converged solution at a give load. By default, this is set to 26 within ANSYS. WebJun 19, 2024 · 1. Turn off the "Trim contact" in contact properties. 2. Change the "Time Step Controls" in contact properties to "automatic bisection".
