Hey, I have a small problem setting up my simulation. I am trying to simulate dispersion in urban area, however I am struggling with applying boundary conditions. I have done some research and it looks like I need to use DPM model in Fluent. In attached picture you can find what kind of boundary condition I want to obtain. I am using file as a source for the particles. Unfortunately, Fluent does not interpret the file as I want it to, as you can see on the other picture. I think the problem is in non-uniform mesh but I do not know what should I do. Do you have any advises how to properly create the particle input file?

P.S. my particles input file has the default format i.e.:

((x y z u v w diameter temperature mass-flow) name)

((-400.0 -150.0 0.804020100503 0.0 0.0 0.0 2e-06 323.15 5.58963715083e-09)inject0)
