Domlim

This option specifies the maximum number of allowable domain errors (undefined operations like division by zero) during a nonlinear solver run before the solver terminates the run.  Such errors are encountered while calculating the nonlinear user defined nonlinear terms function and their derivatives as discussed in the Execution Errors chapter.  This option is used by setting

Option Domlim=number;

Nonlinear solvers have difficulty recovering after attempting an undefined operation.  The default value is 0.
