Normalized Residual Tolerance#
Normalized Residual Tolerance = <float>
Description / Usage#
This required card indicates the value of the L2 norm of the global nonlinear residual vector that indicates termination of Newton’s method (i.e., convergence). The input parameter is defined as
tol, a non-negative floating point number ( tol ≥ 0.0 ) specifying the L2 convergence tolerance for the global nonlinear residual vector.
The Normalized Residual Tolerance card is required; there is no default.
Following is a sample card:
Normalized Residual Tolerance = 1.0e-11
Newton’s method is terminated when the global nonlinear residual falls below tol, or the maximum number of iterations specified in the Number of Newton Iterations is reached.
