sjtusyc is on a distinguished road
I was doing the spray injection simulation.
Water droplets was injected in the static air occupied cylinder by pressure-swirl atomizer with on inlet and pressure outlet.
LISA model and ETAB model was employed.

The parameters for the atomizer to abotain the initial condition of the droplets was;
deltap=0.9MPa cone angle=28.3 radius=1.16mm massflow=0.3251kg/s Density probe normal distance=1mm(I just guess this parameter)


As my understanding,because the continuous phase was static, it should be laminar flow,so no turbulence model should be employed.
But the error message bring up when i run the simulation,that is


" ERROR #002100004 has occurred in subroutine Out_Scales_Flu. |
| Message: |
| The Reynolds number is outside of the range expected based on the |
| Option selected for the TURBULENCE MODEL. Check this setting, |
| the values of the properties, mesh scale, consistency of units |
| and solution values in the input file. Execution will proceed. |
+---------------------------------------------------------------"

Anyone willing to help ,thank you.
I have difficulty in doing this simulation, if someone who have done this kind of work, i am grateful to your advice.
