time variation of cone injection direction

    • ksunil


      How to change the direction of particle injection with time in a "cone injection type". The drop-down options are limited to-

      1. constant
      2. New input parameter

      There is no option of attaching a profile or UDF or expression. I want to change the direction of injection with the time of flow during the simulation.

      Thank you

      You can use DEFINE_DPM_INJECTION_INIT for that or make that input parameter a result of a scheme routine. We are working on making that more straightforward in the future.
      Another way is to have multiple injections with the required directions but the mass flow rate get zero outside the required time interval.
