Steady state flow…
Currently are two calculation modules available to calculate the steady state flow. These are the modules GEONEU and SITRA. The module GEONEU has features that are missing in the module SITRA:

Calculation of a 2D model combined with a partially 3D model

additional potential value in the element centre used in the streamline calculation based on a triangular or quadrilateral decomposition of the individual elements

path line calculation
The notes of the following chapters, however, refer only to the steady state flow calculation with the module SITRA.
