FEFLOW DFE

Hello,

I am trying to represent a pipe in a FEFLOW model. I am working in the unsaturated zone. Maybe I am missing something obvious but I would like to have flow inside the pipe (DFE) but have that area not interact with the underlying soil matrix. Does anyone have any tips? My problem is when I assign my boundary condition to nodes in the DFE the flow leaves the DFE into the underlying matrix?

I would appreciate any help

Thanks
 

Hi Joshua,
Typically, discrete features elements (DFEs) are fully coupled to the matrix. That is the default set-up, i.e. whatever happens in the pipe, it will also happen "outside". However, the exchange between the DFE and the matrix can be controlled. I would recommend you to look the online help system: http://www.feflow.info/html/help75/feflow/09_Parameters/DFE/nodesplit.htm
