Ax, Ay i Az are not computed correctly when running in parallel

[mhadziabdic]

In sequential run, Ax, Ay i Az are correct but there is an error when run in parallel. I noticed this when testing hybrid LES/RANS channel in Test directory. This is produces on 4 processors:

Ax : 6.80034E+00

Ay : 1.31489E+01

Az : 2.03354E+01

and this is given when single processor is used:

Ax : 6.28000E+00

Ay : 1.25600E+01

Az : 1.97192E+01

This has impact on temperature field since the energy balance is not satisfied and energy is dropping.
