solution options in flotran solution options in flotran screetch82 (Mechanical) (OP) 6 Jan 04 15:02 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 mohr (Aeronautics) 8 Jan 04 20:17 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.CheersMohr RE: solution options in flotran screetch82 (Mechanical) (OP) 9 Jan 04 01:46 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 rate2nd: 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.
