Nonlinear differential stiffness update option. Controls the nonlinear differential stiffness update strategy when a non-positive definite error is detected in a nonlinear static solution. The value set is the number of iterations following a non-positive definite error before the differential stiffness is again added to the tangent stiffness. NITERKSUPDATE is only applicable when LGDISP is set to ON, 1, or 2. |
