3D 90 degree elbow

First mesh face using Quad, Submap, then mesh volume.
Interval size: 0.001
Take too much time.
Fail, only mesh the faces

2nd mesh face using Quad, Submap (interval size 0.005), only Stair steps option are available for mesh volume (interval size 0.001).
Workable. Maybe not... still too long...
