Failed to find consistent initial values

I am fairly new to COMSOL and I realize this topic has been covered in the discussion forum, and one of the major problems seem to be that the initial conditions are too far from the final solution.
However, I'm working on a two phase flow problem using the Darcy flow module and I want to start with a 2-D box completely saturated with water (the wetting fluid) into which I introduce a second fluid (non-wetting, with greater density) at a known velocity. The only way I've been able to get the model to converge is to give the model unrealistic initial conditions. Any suggestions would be greatly appreciated.
