节选段落一：
          Type 1 in the Element type reference number.
         Click on Flotran CFD and select 2D Flotran 141. Click OK. Close the Element types window.
         So now we have selected Element type 1 to be solved using Flotran, the computational fluid dynamics portion of ANSYS.


节选段落二：
Go to the ANSYS Main Menu

Click Preprocessor>Material Props>Material Models. The following window will appear
 
As displayed, choose CFD>Density. The following window appears.
 
Fill in 1.23 to set the density of Air. Click OK.

Now choose CFD>Viscosity.


节选段落三：
(VX=VY=0 for all sides)

Once they have been applied, the pipe will look like this:
 
         Go to Main Menu>Preprocessor>Loads>Define Loads>Apply>Fluid  CFD>Pressure DOF>On Lines.
         Pick the outlet line.
