Hi everyone

I just want to simulate a coming flow past a fixed bubble , where a shear-free(zero-shear-stress) boundary condition is imposed at the bubble surface. In this type of boundary condition, the normal velocity as well as the shear stress is zero, I've tried the "slip boundary" in Openfoam, however incorrect results are obtained compared to the theretical results.

Could someone tell me how to set this boundary condition in Openfoam or send me a piece of similar case?

Thanks.
