Nonlinear solver did not converge.

I'm trying to use the Particle Tracing for Fluid Flow. However, I keep getting an error saying the nonlinear solver did not converge, last time step did not converge. I've looked to make sure all of the boundary and initial conditions are defined but am still gettting the error for time dependent studies. What parameters need to be altered so the solution converges?

For another part of the simulation, I need to mix two substances together. Each substance would come from a different inlet, and the sample would leave as a mixture. What would be the best physics module to use?

Thanks!
