solution options in flotran

(OP)
Can some help me with solution options and fluid property options in FLOTRAN for
air flow?

I'd really need some sample calculation as an example.

RE: solution options in flotran

Hi Screetch82:!! :

In order to help you, can be more specific about your problem ???.
Fluids are a very difficult thing to model, validate and solve.

Cheers

RE: solution options in flotran

(OP)
As an simple example I was thinking about a 3d pipe, which has a diameter of 14 mm (for 60 mm lenght) and is decreased to a diamter of 10 mm´. After anpother 20 mm length there is a 90 degree turn. (the measurements don't really matter. since I just want to use it for verification with an experiment)
 
Now I want to solve this  problem in two ways:

1st: I have an inlet volume flow rate
2nd: I was both the pressure of the inlet and outlet and want to compute the volume flow rate and velocities.

I am using air at room temp.  
it be great if you could give me the options (the fldata comand) for both ways and for incompressible and compressible analysis.

I went through the examples but I am just familiar with the si system and I could't find an example of 3d analysis.
I cen email you the imput file I have for the problem..but it has def some errors.
