source term for spray
 

I am simulating spray injection in a direct injection engine. I need to simulate swirl type injection process. For that I need to use momentum source term to initialize the swirl components. I know I need to use SORMOM.F user file. But don't know how to use the built in code for the spray injection from the top of the cylinder ( spray direction downwards in a vertical cylinder )

I need the help of experts....urgently. I appreciate the thank for responding to my query.
