DPM Injection Material droplet

i want to use DPM-Model for spray simulation. If i select injection i cannot set droplet as material type, which i need? In the user guide they say that the material type Droplet can only be set by heat transfer processes. I can only chose for material type massless and inert. Does some have any idea how i can get droplet without using heat transfer process.
I need droplet as material type because i want to inject liquid water.
This is my first post. Can someone help me please? I will reciprocate to you if i can!:)

you can choose the droplet option, then you choose any kinds of material in the up-down list. This material will appear on material window, you turn back material and setting and edit material as what you want (of couse, you do not change the name, you change only the physical properties)

From the FLuent user guide:

The droplet type is available when heat transfer is being modeled and at least two chemical species are active or the nonpremixed or partially premixed combustion model is active.

So you just have to turn on the energy equation and enable species transport.
