flux calculation

  dear sir:

      as shown in the manual that the flux calculated through the 'fluid flux analyzer' is not exact flux values, i get two questions about this flux: (1) whether the error between the this flux and the exact flux is bigger or not ?
(2) if the error is bigger, how to calculate the exact fluid flux?

    thanks

Good luck with getting [i][b]exact [/b] [/i] flux values out of a FE model .... I'd say that's close to impossible. Try to use the estimates that the Fluid Flux Analyzer gives you. That's likely as good as it gets - unfortunately  :(

Cheers, Chris
