Hi, I try to run a transient simulation, with help of experimental data. I want to use experimental data - measured in 3 points nearby an inlet, fluctuating in time - for the velocity inlet boudary condition. I think i have to do this with help of an udf, but how? I hope anyone can help me.. Janneke

hi you could use udf,you will be fitted curve on experimental data then input equation to udf. good luck

can you tell me if there's somewhere an example how to 'input equation to udf', I can't find something in the fluent udf manual? Thanks, janneke

Dear Jenneke My problem is just as yours. If you found any answer please make me known. I will also contact you, if I find any approach. Please send me your e-mail. Good luck, Mohsen. keshavarzian.mohsen@gmail.com
