Default negative temperature problem

Hi,

I am simulating a 2D turbomachinery with the laminar model. The negative temperature keeps occuring. But it is only in a small portion of one cell so Fluent still can proceed until non-positive volumes is found. Did anyone happen to experience this issue before?

Best regards,
Renold

Thank you. I am using PISO method. And I figured out the non-positive volume issue was because of my interface setting.
