Hi @ph1
We are happy to help new users but your question is not clear and I’m not sure why you posted that screenshot… Have you tried any of the MFiX tutorials to get started?

Thanks for your reply, and sorry for my unclear expression. Here is my question:
I have tried several tutorias on the GUI. Now I want to simulate the sparay fluidized bed, but do not find the part I can set three phase on the GUI, so I try to write a udf. In which file I should check and amand?
I’m still not quite sure what you are trying to do, but if you want 3 solids phases, you just add them in the GUI - no need to write custom code
thank you very much!
