UDF using for an averaging parameter

masoud12321 · March 10, 2015, 02:22

hi
I'm trying to write a udf which gives me average-time of parameters and rms (root mean square) like velocity and tempreture over a specific time priode in all domain. and export the result to an exel file.
If this is possible I would greatly appreciate some information.
thank you

You could use a UDF at the end of each time step using the DEFINE_EXECUTE_AT_END(name) macro to save the current variable (velocity, temperature etc) to a data file using comma separated values. Then import this data file into Excel for data processing (time averaging and rms).
