dpm and size of particles
 

i have injected solid particles in a river in order to study how many particles trapped . the diameter of particles are between 1 and 1000µm. the solution is converged when tracking particles having size from 1 to 120 µm but it doesn't converge when the diametre of particles>120µm .can you help me to resolve this problem

Try turning off DPM interaction with continuous phase if you can assume they don't have any effect on the continuous phase.
