These parameters are ignored if the rms-NR-conv option is set to on.
Default: depends on the module.
(reltolerconv (<var> <num>) ...) Relative tolerances for Newton-Raphson
convergence. See tolerconv. The tolerance for a particular variable
is based on multiplying the relative tolerance value by the maximum
magnitude of the variable over the entire problem domain. Default:
depends on the module.
(cutbackmax <num>) Maximum times that a time step is cutback because
of lack of convergence of either Newton-Raphson or preconditioned
conjugate gradient iterations before the run is forced to terminate.
Default: 30.
(rms-time-step <on-or-off>) Turns on or o time step convergence based
on root-mean-square of the estimate of the relative time truncation error. If the error exceeds the tolerance set by rmstolderdt the time
step size is cutback and the time step is redone. The size of the time
step for the next step is based on how close the actual time step was
to the tolerance. Default: off.
(rmstolerdt <num>) Tolerance for the root-mean-square of the estimate of
the relative time truncation error. Default: 0.1.
(rms-NR-conv <on-or-off>) Turns on or o Newton-Raphson convergence
based on root-mean-square norm of the residual vector R. Default:
off.
(rmstolerconv <num>) Tolerance for Newton-Raphson convergence based
on root-mean-square norm of the residual vector R. Default: 0.001.
