Tube Variable Heat Flux -- CFD Online Discussion Forums

azueter New Member Ahmad Zueter Join Date: Jun 2017 Posts: 4 Rep Power: 8	Hello All, I am modeling a tube which is exposed to non-uniform heat flux in angular direction (but uniform in axial). I have the data (Heat flux versus angle) in an excel table and I would like to import it as a piece-wise function (with interpolation) to FLUENT. Well, I have not found any example on how to define piece_wise formulas to UDFs. Also, I could not get how to define the angular co-ordinates in UDFs. Your help is highly appreciated Last edited by azueter; June 10, 2017 at 04:48.
