Why I got negative temperatures in my simulation with LSDYNA (d3plot)?

    • Melissa28

      Hi everyone, I have a problem with LSDYNA. I got negative temperatures in my model at d3plot. My temperature should rise from 20° C upwards and not in negative direction. And I also cant see my plastic deformation. My question is if I did something wrong with initial or boundary conditions? 

      It would be very nice if someone can help me :)

      Which material model are you using?
      Is this a mechanical analysis (not coupled thermal/mechanical) where the change in temperature is due to plastic work?
      You need to tell us more about your model.
