Grid construction and slice extent

Hi !

For my PhD, I want to use FeFlow to model a spring and its catchment area.

The model is a simple three layered aquifer whom layers are cut by the topography. But when I built it in FeFlow, despite the adaptation of the layer to the topography, it appears that all slices remain the same (i.e. they do not be clip by the intersection of topography, as pointed out by grey arrows in the below illustration) :

So the questions are: Is it possible to clip slices (so to have slices with various geographical extents) ? And if is it possible, how to do that ?

Arnauld,

all the slices have the same extent. Please also see forum topic http://feflow.info/forum/index.php/topic,16.0.html, answer number 7:
"How can I model areally limited layers like sand lenses in FEFLOW? In FEFLOW for 3D modeling all layers have to extend
over the whole model area. For modeling areally limited layers, e.g. a sand lense, you can choose between two options: A)
Modeling of the sand lense by changing material parameters inside a model layer, B) Modeling the shape of the sand lense by
two extra slices which in the area where the sand lense does not exist form a very thin model layer with material
parameters of the surrounding stratigraphic layers."

Best regards,
Peter

Thanks !
