kam Guest Posts: n/a	Hi - I am modelling fire inside a room and would like to define the heat transfer coef for the thermal boundaries (walls & ceiling). I want to calculate h coef from the expression h = 1.77(Twall - Tambient)^0.25. Is it possible to do this with UDF? If yes, can you please give the macro should be used or if possible few lines description on how to do it. Thanks - Kam
