Weird results with simpleFoam
 

Hi guys,

I'm running simulation using 1.6.x and SST at Re=40000 using "calculated" nut boundary condition and got this weird low pressure region on the patch of my model:

It appears that this is the only patch to have such problem in the model,

but the pressure reading on this particular patch is essential to the project.
Anyone have any idea what might have caused this?

Thanks,

John
