Does any one have experience in simulating rotating flows, over aircraft due to rotation of engine propellers, using multiple reference frame model in fluent.

Its a 3D problem, and I tried to model it by referring 2D tutorial, since, I have not found any 3D tutorial on this topic.

On first iteration itself, I am getting error saying..

temperature limited to 1.000000e+000 in 1344022 cells on zone 1 in domain 1
temperature limited to 5.000000e+003 in 684418 cells on zone 1 in domain 1
temperature limited to 1.000000e+000 in 1148995 cells on zone 55 in domain 1
temperature limited to 5.000000e+003 in 197246 cells on zone 55 in domain 1
temperature limited to 1.000000e+000 in 1290485 cells on zone 56 in domain 1
temperature limited to 5.000000e+003 in 52227 cells on zone 56 in domain 1

absolute pressure limited to 1.000000e+000 in 208455 cells on zone 1

absolute pressure limited to 1.000000e+000 in 420701 cells on zone 55

absolute pressure limited to 1.000000e+000 in 425312 cells on zone 56


turbulent viscosity limited to viscosity ratio of 1.000000e+005 in 3302882 cells


Can any one help me to solve this problem

thanks
