Hi everyone.

I am trying to simulate the motion of SiC particles in an air filled enclosure in FLUENT. The left and right walls are at 373 K and 273 K respectively and top and bottom walls are adiabatic. Natural convection with just air is behaving fine but I am not able to insert the particles into my enclosure. I want them to be already present in the enclosure at t=0. The particles need to be one way coupled with air and will move as air rotates in the enclosure. I want to perform particle tracking in the Lagrangian frame after different intervals of time. Please help me with how to add 1000 particles with a random initial distribution and zero initial velocity in the enclosure without having to inject them.

Thank you!

You can use file injection. You can check following in help manual.

Hello,

In fluent DPM, particle initial conditions can be read from an external file. The file has following form:

((x y z u v w diameter temperature mass-flow) name ) and file should have extension of .inj
