[Gmsh] Correct .geo file ... but self-intersections in surfaces for 3D mesh ?!?

[David Colignon]

Hi,

at first sight, can you check your geometry (triangles) around points 2804 and 2667 ?

The lines 16488 and 100000063 are also crossing each other. Idem for lines 18341 and 100000064, and there are more of them.

Regards,

Dave
