D-Geo Flow model


The D-GEO Suite D-Geo Flow (D-Geo Flow) model definition.

Add layer

For the geometry it is import to set the geometry points in the correct order. I.e. per polygon, set the points in clockwise or anticlockwise order. Furthermore it is import to add all points which are part or touch a certain polygon. This procedure is automatically done when the user creates a geometry via the user interface. However when the user wants to create a geometry via Geolib, it is important to specify all points for each layer. An example is illustrated below.

The following valid code will produce a correct geometry, note that the clay layer is a rectangular layer, but still requires 6 geometry points. This is because the dike layer touches the clay layer at two points. If the clay layer is only generated the 4 corner points, a valid geometry is generated, however unexpected results can occur.

import geolib
from geolib.geometry import Point
from pathlib import Path

ds = geolib.DGeoFlowModel()

clay_points = [Point(x=-50, z=-10),
               Point(x=-50, z=-5),
               Point(x=0, z=-5),
               Point(x=20, z=-5),
               Point(x=50, z=-5),
               Point(x=50, z=-10)]

dike_points = [Point(x=5, z=2),
               Point(x=15, z=2),
               Point(x=20, z=-5),
               Point(x=0, z=-5)]

soil_clay= geolib.soils.Soil()
soil_dike = geolib.soils.Soil()
soil_clay.code = 'clay'
soil_dike.code = 'dike'


ds.add_layer(clay_points, soil_clay.code)
ds.add_layer(dike_points, soil_dike.code)

ds.filename = Path('geometry_example.stix')
