cfdkdk is on a distinguished road
Hi,

I want to solve balde rotation problem. Its radius nearly 2 meter and its rotational velocity 6000RPM.
But I can not converge this problem with fluent. I use density based option, and decrease courant number but when Its rmp value exceed 500,600 The solution is diverged. The air properties is ideal gas because of high mach number.

Help!!!
