Seepage Analysis in Paratie Plus is mainly conceived to determine pore pressures on the retaining walls. This is an alternative  for all those cases for which simple seepage schemes are not applicable.

An additional purpose of the Seepage option is the calculation of  pore pressures required by a Slope Stability Analysis.

In both cases, the interface between Seepage and non-linear retaining wall module or Slope Stability module is completely automatic.

The Seepage module can be also used just to run a seepage analysis, aiming at assessing water pressure distribution and water flows to be dealt with in any region. So a retaining wall is not strictly required in the model.

The Seepage analysis is accomplished by running a 2D finite element model which is automatically created by Paratie Plus at each stage.

Our finite element solver Xfinest has been extended to allow steady state analysis under both confined and unconfined conditions.

Different permeabilities can be assigned to different soil zones. Different values in vertical and horizontal directions may also be applied.

Paratie Plus  automatically generates typical hydraulic boundary conditions for most common design situations. However more general conditions may be assigned by Users in terms of known heads, known fluxes or prescribed flow quantities.

Simple tools are provided to assess relevant results. For example there is a command to determine  the amount of flow required to accomplish necessary dewatering conditions; moreover the User can perform piping checks (i.e. excessive flow conditions in soils) very easily.
