ANSYS Fluent is a pretty powerful when it comes to Discrete Phase Modelling. In addition to solving transport equations for the continuous phase, with ANSYS Fluent you can simulate a discrete second phase made of spherical particles dispersed in the continuous phase. The options are pretty diverse, but you will be able to compute e.g. the trajectories of these discrete phase entities or as the heat and mass transfer among those,... This article below tells you on the options, and more important, the limitations, you have with DPM simulations with ANSYS -Fluent:
For Wax like fluids specific modelling, i have seen some parafine wax simulations related articles using Fluent such as http://ijens.org/Vol_18_I_05/180505-3737-IJMME-IJENS.pdf that maybe you can look at.
