Hey, all,
I have a question about the pressure boundary condition. Usually people use zeroGradient condition for pressure at wall. This condition works fine for most situations. But I have a sharp corner in my simulation, the this condition will cause a singularity and this corner. The pressure at this point keeps decreasing and never recover.
Does anyone know if there is other condition we can set for pressure at wall??

thank you all in advance.~
