COUPLING AND FLUX

Hi all,

I am trying to understand the “COUPLING” and “FLUX” in the out file, so I used the following .out in the case abdulLab. For the first output, I got values in “COUPLING” and “WDEPTH”, zero “FLUX” in the point1 tecplot file.
For the second output, I got values in “WDEPTH”, “FLUX” and “FLUX_INNER”, zero value for “COUPLING”.
For the third output, I got values in “WDEPTH”, and zores for “COUPLING” and “FLUX”.

So “COUPLING” only works for points, “FLUX” only works for polyline? What does “FLUX_INNER” mean?
Thanks,
Xuan
