Hello,

you can try 
CGAL::Polygon_mesh_processing::experimental::remove_self_intersections()
provided by CGAL/Polygon_mesh_processing/repair_self_intersections.h.

If you only have local self-intersection, it usually works very well.

For listing all intersecting triangles use `self_intersection()`
https://doc.cgal.org/latest/Polygon_mesh_processing/group__PMP__intersection__grp.html#ga6c5bed399d14ddbba820ce50d3145712

HTH,

Sebastien.
