Hi all,

I am trying to model the phenumatic conveying of flyash. For this I am using time step of t=0.005 sec.
Initially everything was fine but after few time steps i got a message that "Turbulent Viscosity limited to viscosity ratio of 1e+05 in 10 cells".
I thought this will disappear as solution become more stable but number of cells increase with every jump in time step.

Please help me out in handling this.

Regards
Shubham
