Maximum number of equilibrium iterations allowed each substep.

One iteration forcing key:

Using one iteration per substep may result in unconverged solutions for nonlinear analysis, and the program may not indicate divergence in this case. This option is intended primarily for use by the Ansys Workbench interface. Keep in mind that forcing one iteration per substep is only recommended under very specific conditions; for example, nonlinearity in bonded penalty type contact. Under these conditions the solution typically converges in one iteration.
