TGNet was an old Scientific Software Intercomp release. I don't know what happened to that one now.

Also they have a free book; “Fundamentals of Compressible Flow” that gives an example calculation set in chapter 8, “Fanno Flow” that may be helpful for validation of the software.
On the negative side, I doubt that there is any significant technical support. But it is free.

Zapster-Thanks for your input. I don't have access to Linux. Note: Fanno is for adiabatic flow with friction and not for validation of transients.

However---
For liquids, there is a possibility that the fluid will go two phase and even choke. The choke pressure should not be calculated by steady state techniques- but by techniques of the method of characteristics.
For gases that initially choke, the choke presssure should not be calculated as a steady state choke condition-but by techniques of the method of charateristics.
Hopefully vendors would use those techniques.
On a past thread for pipe line break, individuals have recommended using steady state calculations for determining exit pressures during a transient. That type of approach will lead to misleading results.

By the zero at the exit plane, I mean zero back pressure.

This thread should end, unless someone can provide vendor contacts-in which my original question can be answered.

It was at http://www.psig.org/Conferences/conf.asp?year=1995, a conference of the Pipeline Simulation Interest Group. Maybe you could give them a holler.
