I've followed the modelling evaporating liquid spray tutorial from ansys. I'm trying to model an atomizer no unlike the one in the tutorial. And have overlooked this step in previous attempts.

I can't locate the 'spray modelling' box for unsteady particle tracking anywhere in my discrete phase model. Is the breakup and stochastic collision the same as "Droplet Collision and Droplet Breakup in the Spray Model group box."
Similarly im unable to ensure Ensure that TAB is enabled in the Breakup Model list. and retain the default value of 0 for y0 and 2 for Breakup Parcels in the Breakup Constants group box.

Thanks

It sounds like you're following a tutorial written for another version of Fluent. According to the Fluent tutorial guide for R15.0, they have only enabled 'Temperature Dependent Latent Heat' and 'Breakup' under 'Options' of the 'Physical Models' tab.

Read the relevant sections of the users and theory guides for a clearer understanding of what these models contain and where they are applicable.
