Assign limit in udf for Temperaure and Pressure
Hello,
I am writing my udf in fluent for material properties. Where I have to assign certain limit for both temperature and pressure in the beginning of the udf. Also this bounded value, I want to use it in other properties in the same udf. Can any one give me some ideas how I can define limit in udf ? Thank you :) BR, -Yogini |

You can establish a loop over either faces or cells and check the parameters you wish. If their values would have exceeded maximum range, you can be informed by an if-clause, for example: if (C_P(c,t) > 1e+10) Error("pressure has exceeded maximum range"); Above command lines will stop UDF procedure. Goodluck |
Hello,
Thank you for your reply. In my case I am using wet-steam udf for calculating thermodynamical properties (like, P, T, Cp, Cv, rho, etc). All are the functions of T and Rho in polynomial form. In my case, the calculated values in fluent increased too much. That's why I want to set a certain limit for Temp. and rho. Like one example, P = f(T,rho), if T > 360 K then T = 360 K else T = T Same for rho also. I want to put this 'if-else' clause in my udf, can you guide me how to write it? -Yogini |
