$StopCriteria Directive
Normally, stopping criteria for iterative numerical solutions are set using the Stop Criteria menu command. The $StopCriteria directive provides an alternative way to set the stop criteria that control the results of iterative calculations. The format of the $StopCriteria directive is
$StopCriteria Iterations=200 Residuals=1e-5 Variables =1e-9 Time=3000
The four parameters correspond to the inputs in the Stop Criteria dialog. Note that it is not necessary to enter all four parameters and that they can be entered in any order or in separate $StopCriteria directives, e.g.,
$StopCriteria Iterations=200
$StopCriteria Residuals=1e-5
The $StopCriteria directive is processed when the equations are compiled and the specifications made with the directive will override any previous settings.
Note that abbreviations are accepted:
StopCrit is accepted for StopCriteria
Iter is accepted for Iterations
Res is accepted for Residuals
Var is accepted for Variables
