External Input Data read as Boundary Conditions
 
Dear CFX- Experts,

I am dealing with a time-dependent problem with variation of the Boundary Conditions by time.
like

Time[s] Pressure Massflow Temperature
1 0.5 1.5 300
2 0.6 1.4 310
3 0.5 1.5 300
.. .. .. ..
.. .. .. ..
.. .. .. ..
2 0.6 1.4 310

I really don' t know how i can set up this problem! Is there a possibility to read extern data in CFX? If yes could you help me? Or is there another option to handle such problems?

Thanks a lot to all

Use a 1D interpolation function. You will need a separate function for each of pressure, massflow and temp. This is easily setup in CFX-Pre.

Hi Glenn,

thank you it is working and I hope the calculation will finish well.
