CGAL 5.4 on Ubuntu 22.04 is raising a CGAL::Precondition_exception because the calculation of submerged triangles results in some arrangements with collinear points.
terminate called after throwing an instance of 'CGAL::Precondition_exception'
what(): CGAL ERROR: precondition violation!
The library requires additional checks that all mesh triangles are non-degenerate, and should handle exceptions gracefully.

$ gz sim -v4 -s -r waves.sdf
Only the spherical buoy needs to be included to produce the error.
