Hi all,

I have a problem involving a 2D flow through a domain 100nm in length and height. There are small 10nm x 10 nm blocks in the domain. The flow is an ideal gas. The pressure drop between inlet and outlet is tiny, only 1Pa. I only know the total inlet pressure, and total outlet pressure. However, the fluent boundary conditions specify a total pressure (guage) for the pressure-inlet BC, and static (gauge) pressure for pressure-outlet. However I know only the total pressure for inlet and outlet, i do not specifically know static guage pressure for outlet.

Any advice on how to set up the problem is much appreciated.

Regards
