[Nek5000-users] Warning Message : L1/L2 DIV(V)

[nek5000-users at lists.mcs.anl.gov]

Dear Developers,

I am trying to run an LES in a turbine blade passage and I ran into this
warning message during my production run:

               L1/L2 DIV(V)    :   1.9224E-01   2.3951E+00
               L1/L2 QTL       :   1.9180E-01   2.3014E+00
               L1/L2 DIV(V)-QTL:   4.3317E-04   6.6792E-01
               WARNING: DIV(V)-QTL too large!

I tried to grep it to the source code and found that the quantity QTL refers
to the thermal divergence ( I do use usrdiv in my outlet ). But my case is
purely from a fluids perspective and does not involve heat transfer. So I am
wondering how QTL would pop up in my simulation.  And I also noted that the
error message comes up only when I use PN-PN basis function. I would like to
know if this error message is a concern at all .

Regards
Shriram
