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. nancy mairs disability audience

"WebIn humans bisecting short durations (<1 s), Wearden and Ferrara (1996) found bisection at the geometric mean with an L:S ratio of 2:1, but with larger ratios, the bisection point was closer to the arithmetic mean. With longer durations in the seconds range, bisection was not at the geometric mean with any L:S ratio, including 2:1 ( Wearden et ... " - Bisection occurred ansys
