[交流] same geometry,structured and unstructured mesh,different behaviour.

Hi guys:

I use the same geometry but different mesh which one is structured and the other is unstructured simulating bubblecolumn via twoPhaseEulerFoam, the other things such as BCs,FVscheme is totally the same.
while running, the deltaT is getting smaller and smaller in unstructured mesh,but delta T is stable in structured mesh. I check the unstructured mesh is OK, and the quality is above 0.36.

can anybody explain this to me? thanks in advance.
