  I am doing randomize injection from a surface in an unsteady simulation. Can i display the location on the surface from where the parcles are being injected in Fluent itself without exporting anything in sample file? I tried but i couldnt. Also, do the injection locations vary at every time step? I tried to press the 'list particles' button on the injection tab and got the attached table. The y and z locations vary with time step for every parcel. Does that mean the injection locations vary at every time step?

  No, they're random, so unless you display all parcels (Particle track) and just look for the "new" ones. Yes. Probably - run another several steps and see.
