Hello,
I'm modeling transient inlet pressure conditions on FLUENT for the first time. The function is rather easy: P=10+2t ; where t=time (s) But I need P to max out at 50Pa. I've read I can do this using User-Defined Functions on C language. Is this necessary? If it is, I should just write the code and make sure to include #include "udf.h" and UDF_PROFILE (inlet_pressure, passed-in variables)? and how would I know what the correct names of the passed-in variables? Also, once the file is written, all i have to do is compile it using the DEFINE window when I start the calculation set-up? Please advise me if I am wrong about anything. Thank you in advance for your help. |

It's more straightforward to use transient profile:
( (pressure transient 3 0) (time 0 20 21) (pressure 10 50 50) ) |
