Dear All,
In my case, I need to reconstruct the data in the folders for different processors. I found that "reconstructPar" is so slow. I have 9-million cells and use 80 processors. For each time step, it needs over 5 mins to even get one quantity. Does this also occur in your cases? Any methods to speed up this process? Thank you very much ! OFFO |

Hi All,
I usually just do this with a bash one-liner: Code:
$ foamListTimes -processor > log.foamTimes; awk 'NR%4==1' log.foamTimes | parallel --halt=0 -j8 reconstructPar -newTimes -time {}: Cheers, Peter |
