      Hello,

      I am trying to inject acetone parcels using a plain orifice atomizer injector into an air flow as shown.

      I keep getting the following error;


      Plain orifice atomizer injector:

      Invalid downstream density -1

      Skipping injection


      Any help would be greatly appreciated.

      Nozzles use some flow properties downstream to detect the regime. Can you show your mesh, location of the injection and add info about models? Are you able to use a supported newer version?n

      The injection setup is shown below, it is a transient case using a discrete phase model with unsteady particle tracking and interaction with the gaseous phase. n

      Assuming the bottom left corner is 0,0 make the injection position 0.0001, 0.0001 as you may have missed the domain due to CAD tolerances. n
