Hello Dr.Witherden, Since our discuss was nothing related to OpenMP or cuda, I think it would be better to open another thread.
So today instead of "u = 20", I used "u = 0.0583090", normalized by the
speed of sound.
I have tried cases such as:
- 2nd order and 4th order (to see result quicker, I chose 2nd order)
- ac-char-riem-inv for both inlet and outlet
- ac-in-fv for inlet and ac-out-fp for outlet
- initial condition of "u = 0.0583090"
- initial condition of "u = 0" with the expectation of seeing movement
of incoming flow profile approaching the bluff body
I have not made it run properly yet. The central plane (y=0) looks like
after 40s - 200s in the cases above:

Seems there is something preventing the incoming flow entering the fluid
domain from the left.
In the case where initial condition of the fluid domain was set the same as
the inlet, the flow is not developing at all.
Would you mind to take a brief look of my ini file and give me some hints?
What is the difference between using ac-char-riem-inv for both inlet and
outlet, and using ac-in-fv for inlet and ac-out-fp for outlet?
I also noticed that in the example case couette_flow_2d, in the "ini" file
it stated that "Uw"=70 and "p=100000". Apparently these values are not
normalized. Please let me know in what situations the inlet velocity needs
to be normalized.
Also, in the 3d_cylinder case (along with the publication), the initial
condition was set like: u = 0.2366431913+0.001*z*yv =
0+0.001*z+0.01*cos(x)*cos(y)*cos(z)w =
0+0.001*z+0.01*cos(x)*cos(y)*cos(z)Is there any meaning behind them or they
were just optimized to push convergence? In the case, seems like not only
"u", "v", and "w", "x", "y", and "z" are normalized values as well. Thanks
a lot!Best regards,Junting Chen <about:invalid#zClosurez>
