#Feflow 6.2 software#

FEFLOW is able to model two-dimensional and three-dimensional geometries with one to several layers. A simple geometry can also be produced in FEFLOW. In FEFLOW, the complex geological model of the hydrogeological characteristics is preferably imported to produce the geometry of the modelling area. The division to smaller elements allows accurate representation of complex geometry, inclusion of dissimilar material properties, easy representation of the total solution and capture of local effects. It uses Finite Element MethodВ (FEM) technique in discretization of the continuous domain modelling area into set of discrete sub-domains or elements.
