Issue arises when a regulator is defined as a single three phase object as in the CYME IEEE123. CYME and GDM allow this definition but when this is written to OpenDSS, three Regulator controllers (defined for each phase) act on the single regulator simultaneously, causing convergence issues even before the controls are turned off for the tests.
A few options exist:
Change the CYME model and explicitly state lack of support.
Auto-separate the regulator by phase at the CYME reader
Deal with the separation at the OpenDSS writer step
