Bisection occurred ansys

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 4, 2024 · Knowing that the parts should be initially in contact, one simple adjustment is all that is needed to close the initial gap and allow the simulation to successfully solve. The adjustment is to set the Interface Treatment in the Contact Details for the contact region in question to Adjust to Touch: This change automatically closes the initial ...
