Particle Tracing in Fluid Flow

$

Hi all,

I want to simulate particle laden flows considering coupling between both- the particle and the fluid phases. I'm currently using the following two modules: Laminar flow(spf) and particle tracing module for fluid flow(fpt).

After importing both the modules in my model and checking the boxes for both of them in Study1> Step1: Time Dependent> Physics Interface and then computing Study1, I find that it doesn't consider the particle phase.

When doing the same for Study2(i.e. checking both boxes), it doesn't work and gives the error:

"Failed to find time step so that given tolerances are satisfied.
Time : 0
Last time step is not converged."

Please help.
