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. WebThe product of the response eigenvalue and the previous time step (Δt n) has been employed by Hughes() for the evaluation of 1st order explicit/implicit systems.In Hughes() the quantity Δt n λ is referred to as the “oscillation limit”, where λ is the maximum eigenvalue.For unconditionally stable systems, the primary restriction on time-step size is … WebSep 12, 2024 · There is an abundant of options in ANSYS classic when one wishes to post process results.
