SMS:ADH Model Control Solver

This window is part of the ADH model control dialog (ADH | Model Control... command). It is accessed from the Model Control window by clicking on the Solver tab.

(As noted at the top of this dialog, this is an advanced feature and we recommend that only users working with the ADH development team use these options.)

Linear Iterations By Solver

This window includes the options to control linear iterations in ADH. The controls are similar to the controls for non-linear iterations included on the Iterations tab.

The distinction between linear and non-linear iterations are described in some detain in the ADH users manual.

Maximum number of iterations (IP MIT and IP FLI cards)

In this edit field the user specifies the maximum number of linear iterations that ADH will try for each non-linear iteration.

SMS writes either the IP MIT or IP FLI card based on the setting of the If internal linear tolerance is not satisfied radio group.

• IP MIT card is written if the Stop the solution option is selected. (Recommended)
• IP FLI card is written if the Proceed to the next non-linear iteration option is selected.

The IP FLI card instructs ADH to continue with the solution as if it had converged. This is not recommended.

When the Stop the solution option is selected and the solution has not converged at the maximum number of iterations have been attempted, ADH will treat the solution as diverged and the non-linear iterations will be aborted.
