Two-Phase flow
 

I am currently trying to simulate two phase flow through microchannels using FLUENT..I am trying to solve for laminar flow with constant heat fllux along the walls with unsteady flow..IN this case i am using Eulerian model along with its UDF boiling-rpi-model.c but the solver is not iterating its showing a fatal error..
Pls can anyone give me an idea how to go about..
