    ERROR(ORPSIM-15143): Voltage source and/or inductor loop involving X_U1.E2 Reply

    I am trying to design a DC DC converter using Texas Instruments LM5119. and I keep getting this error, i have added a series resistance to both ends of the inductors that i am using, but i still get this error.

    I am using a transient model of the IC that they have on their website.

    Also i tried using another inductor from the newer coilcraft libraries, but still got this error.

    here is he simulation report, any help would be appreciated

    So i checked by removing inductors, still got this error, placed a 1k resistance in series with main voltage source of 50vdc, still this error. does any one knows what is happening?
