Function gmsh_sys::gmshModelMeshSetOutwardOrientation

pub unsafe extern "C" fn gmshModelMeshSetOutwardOrientation(
    tag: c_int, 
    ierr: *mut c_int
)

Set meshing constraints on the bounding surfaces of the volume of tag tag so that all surfaces are oriented with outward pointing normals. Currently only available with the OpenCASCADE kernel, as it relies on the STL triangulation.
