I would to make a 3D moving mesh simulation ([beginner]) for my master thesis.
I have created already the model in ICEM CFD now. I need to simulate 3D box (chamber filled with air pressure) with a cantilever which opens up to let the air out through a small hole into the atmosphere from a closed position. The cantilever max deflection is <1 degree.

I need to know how to do the moving mesh. Would someone be kind enough to give me an idea where to start with etc?

Unfortunately, I am under time constraints; can only spend 2-3 weeks on this. Would be great if someone can guide in the right direction.
Many thanks
