Unsteady Simulation from steady Solution

Hey together,
I use the solution of the steady simulation for my transient simulation, so it is my initial condition. At the inlet, I consider the total pressure, which changes over the azimuth angle. As far as I know, the boundary condition in the steady-state simulation must be the average. As a small example with simple values. At an azimuth angle of 0 degrees I have 1 bar, at 90 degrees 2 bar, at 180 degrees 3 bar and at 360 degrees 4 bar. I consider this boundary condition in the transient simulation, which also changes with time. It is in itself a shock wave. In the stationary simulation, I now form the average for this. This would therefore be 2.5 bar, which is constant over the azimuth angle, correct? Or in other words, is it necessary to use thew average values in my steady simulation, it somehow makes no sense. greetings |
