nonlinear static analysis in sap2000

[ELSARWAN]

Dear experts,
I am using sap2000 v18 in design steel according to aisc 360-10 and as code required for all load combinations we must perform second order analysis including p delta effect , and the problem coming here sap is taking very long time during analysis, I want to know if there is any parameter in nonlinear parameters option can changed in order to speed the analysis up ,
I am waiting for your help,
thanks in advance.

Depending on the selected no-linear algorithm, the steps count can be reduced, as well as the convergence tolerance can be set to a greater value.
