Thanks it seems manifold ids are set correctly now. But I still get "point is not on manifold" error now even with big tolerance.I think my coarse mesh conform to the geometry similar to the bow_surface in step-54. The IGES geometry is generate by COMSOL, and mesh file transformed from COMSOL to msh by gmsh.
