Can anybody please tell me what DUPLUS is the the following UDF file?
http://my.fit.edu/itresources/manual...udf/node52.htm I am trying to model my wall function such that in the log-law region, u+=(1/kappa)*log(y+/y0+) where y0+ is z0*utau/viscosity. z0 is just some value i will input. Can anybody help me program this macro? or at least guide me how to do it? i have read the UDF manual and i'm still clueless. Please advice thank you |
