> I have a mesh and I want to insert a borehole as a polyline from a geometry file without remeshing to include the line.

I am a new user of OGS6, and I have some suggestions about your question.  
First, I think, in OGS6, the gml file is better to match your msh file. And if you want to insert a borehole, I suggest you try the `Boolean` command in Gmsh.  
I have some similar files, you can download in this topic.[Usage of the constructMeshesFromGeometry tool](https://discourse.opengeosys.org/t/usage-of-the-constructmeshesfromgeometry-tool/771)  
More reference about Boolean in Gmsh, you can find in Gmsh manual and Youtube. I hope I can help you.

Best,  
-Rui
