Hello to everyone,

I am a new user to cfd, and currently for my thesis I am given a CAD geometry which has a turbine blade and its NGV's upstream.
The problem that I am facing is that I can't find a way to create a flow passage.
To be more specific, if you watch this video
https://youtu.be/kHc2-6d5jR0?t=35s
you can see that the fluid passage is very well defined (see the image below).
.

So is there any way to create this block (fluid passage) given that I have the 3D geometry of my turbine?
I have seen many videos on youtube like this,

but the problem is that I can't work it out for my case.
So will anyone help me please?

Thank you!


Update 1.
So somehow I have managed to create the flowpath with the help of this video https://www.youtube.com/watch?v=LCnzYqjmCvA, but now another problem rises. Since I have NGVs I would like to take them into consideration in the flow path. Any ideas how?
