How to setup boundary condition with couple solver

JINHUI

Hi everyone,

I am trying to solve a supersonic/hypersonic flow with

FLUENT and then compare with my own code. I will intiate

a shock at the inlet. The shock will travel towards the

wall with parabola shape,bouncing back and get focused.

I will set the inlet boudary condition with velocity,

pressure and density according to my shock strength.

I am trying to use couple solver with "velocity_inlet" B.C.

However, I could not find how to set the inlet velocity at

same time with inlet pressure. And by the way, what does

the "outflow gauge pressure" mean ?

Thanks
