How to force coalescence in Lagrangian simulation
 

Hi, I'm working with STAR-CD v3.26 (Windows platform) and I'm simulating a mechanical blender in transient analysis where I inject two different droplet type (Glue and Fibre of wood). I have to superimpose a coalescence when two parcel collide. I'm trying to change parameters in Advanced Collision Model but I thing the best way is to operate via user subroutine. Does anyone ever solve this problem? An easy subroutine is also appreciated to start in the right direction. Thank you.
