Iterative Methods in SSN

This section explains the new iteration feature of ARTEMiS (available with version 7 and later).

With this option, users can run real-time simulations of Surge Arresters (often called Metal Oxide Varistor or MOV) and common switches with iterations to ensure the global accuracy of the simulation.

These iterations are different than the ones that SSN makes inside each group. The new iteration methods are global, meaning that a change of the segment or operating point in one SSN group forces a global check for iteration among all iterative groups.

The use of this new iteration feature is determined, for MOV, by the use of a specific MOV block in the ARTEMiS Library and, for switches, of a specific NIB connection.

We call these simulation methods iMOV and iSWITCH respectively.
