Moving Part of Boundary Condition
 

Hi and a good morning everyone,

I have a beginners question:
I've done a few simulations using bouyantPisoFoam. We are dealing with a building entrance and the flow that occurs if the door is opened. Up to now, I have simply used separate initial conditions for inner and outer volume - so in fact opened a sliding door at t=0.

We would like to do a more detailed analysis and therefore are wondering whether its possible to include a moving door in the simulation so that say the door slowly opens at t=0 and is fully opened at t=3s.

From what I gathered a moving mesh is not what I am looking for but rather a moving element within an existing mesh.

We would really appreciate further information on this,

Many thanks,
