set experimental data as boundary condition
 
I have a text file which has hourly data variation(Time varying data) of temperature I want to read this data from the file using UDF or any other option and set the data file as boundary condition.

TIA

U can write an UDF for that by defining profile as Macro.... In which u r doing this analysis can u tell me this....

With regards, Raj

I am using TRNSYS for simulating building performance for this i have to calculate hourly ventilation and infiltration exchange rate this is not possible in TRNSYS so i have to use fluent as i have very little knowledge of UDFS and fluent can you please write an example UDF for me to understand how to link the hourly temperature data file to fluent boundary caondition
