Dear Guo,
There are two problems associated with this, first is a simulation in vessels which can require sparse data handling (depends on your dx and domain size. The second might be particle dynamics. If particles are passive scalars then it is simple, otherwise it would require fsi which is not yet implemented (but contributions are welcome).
Perhaps, if you could sent a mesh file and describe the physics I can give you more information.
the best mk

Dear mk,
Particle simulation using Euler-Euler or Euler-Lagrange methods will be fine, my concern is the first one. human airway is a very complex shape with a large variation in size, and I haven't finished the airway mesh yet. I want to decide in advance what methods and procedures are needed, because airway simulation requires very large computational resources, and if the program can't do the calculations fast enough or can't adapt to the complex shapes, I will have to changes to my airway model.
Many thanks, Guo Weiqi
But I have completed some simple alveolar models, they are in stl format and I have sent them to your email. I simulated conditions where the inlet is an airflow with a velocity cycle change and the outside is a defined air pressure with a 10 micron diameter particle entering through the inlet.
