I am using fluent 19.0 for DPM simulation. I have a steady state flow field solved already. I want t release particles from a surface (i.e. inlet) and track their movement. However, fluent automatically release 1 particle from each face element on that surface. I would like to release certian number of particles from each face element on the surface according to the area size and mass flow rate of that face element.
Does anyone know how to do this with UDF except providing an fiel for injection? There will be thousands of particles and it is difficult to generate that file for each simulation.

Have you looked into Group injection on Fluent? Or perhaps, a cone injection? Please have a look at section 23.3.1 in the Fluent Users Guide.
Could you please elaborate what you are trying to model?
