      guys, is my step true? i hope you can corrected my step.


      this is the conditional experiment. so my step :












      why if i set operational condition pressure and desity this notif show and the result error??

      Hello, 


      What is the end goal of your simulation? and you sure of acceleration due to gravity is in positive X direction? 


      Regards,

      my goal :


      1. leght tip penetration


      2. angel spray


      3. suter mean diamter


      yes, because in my feul spray i assume to x direction

      The input for the particle diameter is wrong. If you don't know further details but injector type use one of primary atomizer models.

      i use injector by 0.17 mm hole diameter  so i input my particle diameter 0.00017 m

      what do you think in my case, what is atomizer model should I use? plain-orifice atomizer OR pressure-swirl atomizer OR flat-fan atomizer OR air-blast / air-assisted atomizer OR effervescent / flashing atomizer

      In the description it does only refer to hole diameter. Kind of atomizer should be known otherwise you need to make assumptions or resolve the primary break-up region
