How to read transient data as inlet velocity boundary condition

hemmt · December 21, 2016, 05:07

Hello every one,

I have velocity profile (atmospheric boundary layer) data for each time step, saved as .csv format(rows represents values at different height and columns represents values at different time step).
I need to use this file as inlet velocity boundary condition in FLUENT.

So please suggest me how can I make UDF to use .csv file

Thanks

Have you tried using a transient profile? It does not require a UDF. See section 6.6.5 of the Fluent user's guide.

Thanks sir for your reply.

Actually My Profile data is not uniform Spatially. it is varrying with the height of computational domain.
so for this What I need to do.
