      NLAD does not support auto-asymmetric contact behavior or small sliding algorithm. Hence, if model includes symmetric nonlinear pairs, it is possible that auto-asymmetric is deactivating the current pair when NLAD is off, but keeping both pairs when NLAD is on. Also, perhaps small sliding is active when NLAD is off, but it is disabled with NLAD is active. The solve.out file should record these setting. Check the solve.out file carefully.
