smoke distribution modelling
Hi Experts,

I am modelling the smoke distribution in a train tunnel. This is a transient analysis, and I have two doubts. 1. I want to model fans as constant momentum source. I am not getting the units of momentum source in the input box. 2. I am getting the warning of 'turbulent viscosity is limited to viscosity ratio of 1E5. This region is the wall of tunnel.

How to resolve this issue.

Thanks in advance.
