CFX domain error message about multiphase model
 

Hi,

I am trying to setup coal particles inject through a long pipe into a combustor. When I define the domain: Fluids list: air at 25C particle tracking: HC Fuel

an error keeps showing: There must be an object of type "MULTIPHASE MODELS" in the object "/FLOW/DOMAIN:primaryfeed" but it does not exist.

I tried to change the Fluids list to ' Gas Mixture', the error's still there.

Could anyone please tell me what's wrong?
