    negative temperature results in transient heating model

    Brent Boudreaux

      I have a transient thermal model of a PCB with intitial temperature at 50 Celcius.

      There are 43 chips on the PCB; each contributing 9 watts.

       

      But after running the model, it showed some negative temperatures on the PCB?

      What could I be doing wrong?
