how to use timeVaryingMappedFixedValue
 

Hello All,

I need a fully developed velocity profile as an inlet boundary condition so at first I want to develop this profile in a straight pipe and use the outlet values.
I believe that I need to use timeVaryingMappedFixedValue patch in my 0/U boundary condition for velocity in the target case. And as I read the other threads, the outlet patch coordinates should be the same as the inlet in the target case (this is true in my case). According to the tutorial in the pitzDailyExptInlet, I need two dictionary that I do not know how to extract from my initial case (these are obviously the data on the outlet patch in the initial run): (i) the points dictionary in the boundaryData folder, and (ii) the U dictionary in the 0 file.

I have already checked several threads here, but could not understand how to get these data from my initial run (e.g.: http://www.cfd-online.com/Forums/ope...tml#post245855)

Thank you very much in for your help in advance.
