Detailed Example: Cutoff Interface

The cut-off wall example highlights the functionality of an Interface Material Model within a SEEP/W analysis.

Ideally, materials that are relatively non-conductive, or otherwise impermeable, should be accommodated in a finite element analysis by excluding the material from the domain (i.e. leaving a 'gap' in the domain). However, including the impermeable material is often required for presentation purposes or some other reason.

The cut-off wall example makes use of the Interface Material Model, which can be assigned a normal and tangential hydraulic conductivity equal to zero, making it impermeable. The other material models in SEEP/W do not permit hydraulic conductivity to have a value of zero. This ability makes the Interface model rather unique. Moreover, the Interface Material Model has a variety of other uses, particularly if a material promotes flow in one direction (e.g. concrete facing on a dam).
