Reply To: Flat Fan Atomization Model: Warning: atomization model is not valid…

No, it's still single phase unless you switched anything else on - DPM isn't "multiphase" in the same way as the VOF/Mixture/Eulerian models. There should be a surface tension option in the DPM materials though. It looks like some of the fan break up maths is covered in the sheet break up section, https://ansyshelp.ansys.com/account/Secured?returnurl=/Views/Secured/corp/v241/en/flu_th/flu_th_atomizer_pressure_swirl.html
