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
