Be sure to try using the Alternate Solver as Andy suggested. This option must be set manually (cannot be set in the simulation commands on the schematic) and it is easy to overlook it having been set

A lot of simulators have added POP/PSS (Periodic Operating Point/ Periodic Steady-State) solvers to their repertoire. Micro-Cap recently added POP capability. They discuss it here:

Are people using LTxxxx models to simulate RHxxxx. For example, are people using LT117 models to simulate the RH117? Are people happy with the gain/phase margin accuracy of the LTspice regulator

dear A.S. I believe my answer was correct with respect to programs labelled "SPICE". And you can research too. Hank McCall

Thanks for the feedback. This is happening on the latest version I downloaded and after I hav set all sim variables to default in the tool tab. I will try the cap idea and see how it works out.

Thanks, but that was one of the first pages I found when I first started to research the history of SPICE. Yes, it *is* a good reference and worth a read. I really should add it and some more of the
