Only if inviscid model, errors re temp limit, FPU
 
I'm modeling a simple geometry with air flowing through it and trying different "viscous..." models with energy (heat transfer) on. All work nicely, except the "inviscid" model generates errors below. I'm setting temps on three boundaries in the several hundreds, and limiting temp to 200 to 700 range. Is there some special interaction between inviscid models and temperature? Or some other special sensitivity of inviscid models to floating point errors?

temperature limited to 2.000000e+02 in 1808 cells on zone 2 1 Error: Floating point error: invalid number
