Hello,
I'm beginner in using CFD in general. I have few questions. I'm using Inventor 2015 to create geometries for simulations. And the first question is: Lets say that I have some random tube (dimensions are not important) and I import this geometry to CFD program. Is it possible to somehow "fill" the inside of the tube by air or do I have to create geometry of the air volume? I know that CFD works with air volume, but this would realy make my job easier becouse of complex geometries which I'm working with. I'm not sure if I'm expressing myself correctly. I hope I do.
Second question: I have geometry of underslot channel(cross section 25x30mm, 1455 mm long) from rotor of turbo generator (one inlet (axial) and several radial outlets) My task is to figure out pressure drop in this channel. Will it work, if I set boundary condition of outlets to 0 Pa and boundary condition for inlet to for examlpe 20 m/s. I'm not considering the rotation for now.

Hi, I am sure we can help here:
Thanks,

Thank you for a quick answer. The thing is, that I tried to import the geometry, but it doesn't fill itself automaticly. I've tried to set inner volume as AIR but, ther was no volume. Is it possible, that I have to set something in settings?
It is all automated, are you certain that the volume is 100% sealed?
Feel free to share a CAD file.
Well, as you replied, I went to check the geometry and I indeed found smal gap. It is working well, now. Thank you again.
