flow rate of scalar ...
 

Hi,

I am trying to monitor the flow rate of a scalar through an interior boundary. I used monitor->surface->flow rate of UDS. However, by any reason I couldn't get the right flow rate. Everything in the simulation (mesh, definition of diffusivity, turbulence modeling, trasport of scalar, etc.) seems OK. Does any of you face with similar problem before? Any help will be appreciated. Thanks.
