Discrete Phase Model(DPM) interaction/ particle treatment/ injection

  Hello,
  According to the ANSYS Fluent User Guide 2020R1(page 2097), if I choose under-relaxation factor 0.5, 20 continuous phase iterations per DMP iteration, then 10 source term updates are required for the DPM sources to reach their final value. So, at least 200 continuous phase iterations are required after any change to DPM sources. Do I need to select the 200 Max Iterations/Time step during the 'Run Calculation' for the above case?
  Or, what will happen if I select the 50 Max Iterations/Time step for the above case?
  Moreover, which source update will ANSYS consider if I select ' update DPM Sources Every Flow Iteration' and a value in 'DPM Iteration Interval' together?
  Regards,
  Anadi

  Hello Keyur,
  Now, I notice that I mistakenly posted the same discussion twice. But, I didn't get any reply from anyone to my question. Will you comment on any of my posts?
