Default Shock Tube Modeling

Hi All,

I am a new user of CFX. I am trying to model complete shock tube for the wave/gas dynamics. I would like to know how the boundary condition at the interface of driver and driven gas can be prescribed. (Driver & driver gases are different and the pressures, temperatures are different!)

Thanx alot in advance !!

Best Regards, Krishna

It's called initial conditions. It can be described easily using a CEL expression (preferred), or by using seperate domains and giving the domains different initial conditions.

Regards, Glenn
