Improving Robustness in consideration of changing material properties

I have successfully built the skeleton of my model! However, when I alter the material properties (dynamic viscosity and density in this case), the model stops working. I mean major alterations, in the ballpark of 1-3 orders of magnitude. Is there anything other than mesh size and time step that I could change to make this work?
One idea is in the scaling of variables. Does comsol change its default scaling values as I change the property values? Does anyone have experience with manually adjusting scale?
Just to recap, I have a model that runs well, but it only converges quickly with certain material properties. As I alter these properties it takes longer and longer to converge until it starts failing at t=0.
Any help would be appreciated!
