Meshing a borehole path in 3D box as exact internal edges
I am working right now on two boreholes which are represented each via a polyline in a geological body.
My problem
 Assign groups in the partitioned geometry

Best regards and thank you in advance!

just wanted to update that my problem is solved. Here the solution if in future anyone else will have the same issue.
First of all it needs to be mentioned that the Netgen Algorithm doesn't recognise the borehole path as internal edge very well. The solution is to extrude the polyline of the borehole path in two perpendicular directions (select option "both directions"). The intersecting line of the two created faces is the boreholepath (see picture).
Here the workflow:

Create the vertices of the Borehole path

Create a polyline (not spline) through the points of the borehole path

Extrude Path in two perpendicular directions, e.g. XVector and YVector. The borehole is then the intersection line of both planes/faces

Partition Reservoir by the vertices of the borehole path, the polyline of the borehole path and the extruded faces of the borehole path


Mesh faces of the extrusion
