PCL Error: A segment and a facet intersect at point_(for 3D meshing)
Hi Christophe, I have recently started using Gmsh to make 3D mesh of a self-overlapping extruded disk (like entangling pipe). When I make 3D mesh, I get these errors:
Error : PLC Error: A segment and a facet intersect at point
Info : (2.75403e-12,0.549873,-0.118032).
Info : Segment: [9395,9382] #-1 (0)
Info : Facet: [55,2422,54] #7
Error : Invalid boundary mesh (segment-facet intersection) on surface 7, intersection (2.75403e-12,0.549873,-0.118032)
Error : No elements in volume 1 12
Info : Done meshing 3D (Wall 0.425392s, CPU 0.425333s)

Error : ------------------------------
Error : Mesh generation error summary
Error : 0 warnings
Error : 3 errors

Could you please suggest me how to solve this issue? I'm attaching my code here.Test_fiber_turn.geo
