Hi guys,

I hope someone will help me! I have this problem: I have a tunnel long more or less 100meters and some air inlet points on its wall at a fixed distance. Inside this tunnel, objects moves with constant velocity of about 3 meters per minute.

My idea was to simulate only one part of this tunnel with a fixed position for the body inside and translate the boundary condition in order check the effects of the air inlets on the body.......
Other possibility is to move the body inside the tunnel but it increase critically the number of elements and makes more complicate everything.

Quite complicate but I hope clear.

Anybody have some suggestion?

Thank you in advance,
Matteo
