Hi.

I'm trying to get difference of pressure distribution according to various solution viscosity using steady-state simulation.

However, the distribution always display same image like below... (i compared two solution with viscosity of 0.01kg/ms and 5kg/ms)



I expected.. higher viscosity solution show uniform pressure distribution and lower viscosity soltuion show bad pressure distribution.

And standard deviation of velocity should be bad in low viscosity solution.



In case of transient simulation, the difference is clear like below image..



but, transient simulation takes so long time. (cause I need lots of datas)



So, i want to compare pressure distribution using steady-state simulation.

Could u give me some opinion what i am missing in steady-state simulation?
