Sneeze boundary condition

Hi. I’ve been trying to set a sneeze simulation in a conference room, and i have some good results. However I would like to know if its possible to set the sneeze velocity inlet just for a couple of seconds. I want that the sneeze only last a second or two during the simulation. I am using incompressible model, k-epsilon turbulence model, and transient state.

Hey there!

The boundaries you have chosen look quite good to me, what you have to make sure though is to probably improve the mesh quality and also make sure you don’t run into problems with the CFL number (more on this number here).

@CFD-SQUAD, could you also have a look at his setup and propose some adaptations (if needed apart from the ones mentioned already).
