Hi, I 'am writing some UDFs for specifying some thermal boundary conditions under transient case (for example ,heat loss to ambiant, evaporation,....).However , these conditions are changing with time -we use mostlty meterological data (ambiant temperature,sky tem humidity...)witch are presented under tabular form at fixed intervals(every Dt hours). Please can you telle me what is the best procedure to read these data?

Thank you very much. Please advice me.

For Example (Tabular file)

Temps Humid(%) Tambiamt 1H 70 280 2H 80 290 3H 50 285 4H 90 78 .. . . . . . . . .

Heat loss for ambiamt:

HL(T=i:1..n)=F(Humid)*(T_face-Tambiant) for calculing HL i write a UDF Profile

I want to read tabular file and compile the UDF(profiole UDF) .(these conditions are changing with time -we use mostlty meterological data) . Thank you

Test!

Hi,

As I understand,you want to read a transient data file into Fluent.This can be done through a transient profile file.The data has to be in a specified format required by fluent.

Hi Sri, Yes ,i want to read a transient data file into Fluent.but I need some more details to write UDF profile. Please ca n you read , or let me some infdormation about (a transient profile file)specfied format for file data

regards

Hi Sir i found the transient profile file but in my cse i can't use because inneed a function toi calculing losses heat as a function, thank you for your help
