Pitz Daily oodles pressure field problem
Hi,
I was trying to run pitzDaily tutotial case under oodles (OF1.5.x). The pressure field is not making any sense to me. The pressure field is switching between +ve to negative values throughout and changing from time step to time step. I changed the fluctuation scale value in turbulentInlet boundary condition of U to (0 0 0) and then I was getting consistent pressure values. why would this happen? Is the pressure BC at the inlet wrong ? I tried oodles on an external flow sim where forces were important and I was getting similar fluctuation in field, ( drag and lift oscillating in random). Anybody has some insight on this? Thanks, Prapanj. |
