  Hi! how do i simulate how cough droplets/particles move around the room while airconditioning is on? i've done simulation on airflow while on steady and cough particles while on transient and dpm but I don't know how to simulate both simultaneously or how they are combined on animations.

  Hi,
  I recommend you to read the tutorial to gain some thoughts for combining both: Chapter 20: Modeling Evaporating Liquid Spray (ansys.com)

  Thank you

  To add, have a look for cough on here - we've done a load of work on the spread of COVID, as has Bert Blocken (TUV Eindhoven) so there are threads here and movies in the Ansys blogs.
  For the how, you need to decide if the cough will effect the bulk airflow enough to matter, and then track the transient particles on (possibly) the steady flow. Saving images every some iterations will give you the droplet positions for use in a movie, or you can try the Fluent animation tools.
