surface integral on inlet wrong
 

Hi

I am doing some calculations with compressible flow. I found a strange error while trying to get static temperature on one of my inlets: area- or mass-averaged static temperature on inlet boundary is HIGHER than total temperature on inlet bundary.

I am using pressure inlet, uniform total pressure and total temperature, flow is normal to boundary.

Later I realized that area- or mass-averaged velocities on this inlet are also reported wrong: average of axial velocity, x-velocity or velocity magnitude (which in my case should be the same) are reported different and up to 50% too small. On the other side, facet averages are reported correctly, also coloring for vector plots is correct (x-velocity = axial velocity = velocity magnitude).

Has anybody experienced something like this? Perhaps it's due to very small inlet (it's a cooling hole) with small elements.
