I have been working with fluent since version 14. In versions 14 and 14.5 the 2D axisymmetric solver worked very well for simulations of evaporating droplets (ethanol droplets in my case). Since version 15, however, the droplets seen to go crazy once they enter the domain... not following the gas flow (even though the coupling is activated). I was hoping the new version was going to fix those problems but that doesn't seem to be the case (I actually have been trying the run these simulation in all versions since 14). Does anybody know if there was any changes in the solver for the DPM from version 15 on?
