Fluid flow with a moving solid object/hole

Please login with a confirmed email address before reporting spam

Hello,

I would like to model the airflow in a room occupied with people, and to allow the people (cylinders) to move around in the room. Is this possible in COMSOL?

For a silly example in 2D: I have a rectangular domain with a circle inside. Two opposing sides of the rectangle are defined as inflow and outflow for a turbulent flow physics respectively. How can I make the circle change position inside the rectangle as a function of time?

Any help much appreciated!

/Daniel

Dear Jean-Paul,

I wolud like to have a look to your simulation "ACO 2xMOV OBJ 1xSliding along W Auto-Remesh 2013-05-30NS" but I can´t open it, because I don´t have the "pressure acoustics, Transient (actd) module " license. Could you explain me how to put the object moving?

Best regard,

Diana Fidalgo
