Stress free boundary condition

Hi everyone, does anyone know what is a "stress free" boundary condition? and how do you set that in fluent? I'm going to simulate the blood flow in a model of thoracic aorta. I've read some papers in which they talk about this stress free outflow BC to impose at the outlet. I've searched around but could't figure out what stress free boundary condition exactly is and how to impose it on fluent.
Any help would be really appreciated! thanks! |

The outflow boundary condition in Fluent does have zero streamwise gradients. But I haven't yet heard of a "stress free" boundary condition so it would be nice to have a concise definition.
