This is really basic, check the User Guide, 7.3.14 Wall Boundary Conditions, Wall Motion paragraph. All the methods discussed here set in fact the motion of the train. The latest approaches...

If your tunnel has a simple surface (like a cylinder for instance), then you don't need to use even the MRF approach. Just set translational velocities on the walls of the tunnel. So, setup a...

If you need a relative motion between the walls of the tunnel and train, then you will need some sort of moving mesh approach. If you want to setup the problem as a...

Why do you want to use dynamic mesh approach for this problem? Just set the inlet velocity to 12 m/s, zero gradient outlet, walls on the tunnel and train, and start iterate.

I'm curious how are you going to define the motion, if you don't have time as a variable in your computation? In any case, the macro DEFINE_CG_MOTION needs time as input variable, so, I don't expect...

For this case I would suggest a sliding mesh approach instead of the dynamic. You don't have to change anything (maybe the definition of the interface between the 2 rotating domains), on the...
