Any library to calculate <u'> ?
Hi all,
I need to calculate u' ( i.e. (Umean - U) ) for all times and then want to calculate average <u'> . All this is needed for a simulation already completed ..i.e as a postprocessing job. Does OpenFOAM have any libraries to do this? Thank you. Atm |

funkySetFields -create -field Udev -time 0: -expression "U-sum(vol()*U)/sum(vol())" For averaging those I must admit I'm currently not aware of a readymade solution |
Bernhard,
By UMean, I refer to the "UMean" file which is the time averaged velocity which I get in the time step folder after the fieldAveraging library is used. So I want to do U (file in the folder) - UMean to get u' , v' and w' for every time step. Then , if possible obtain time averaged quantities <u'>, <v'> and <w'>. Can funkyset do this? Thanks ! Atm |
