The Curvilinear Hex Core meshing tool is designed for tube style systems, for example
exhaust tubes, in which a centerline of the geometry can be generated easily.
The core of the model will be meshed with hexa elements, which are aligned to the user
defined centerline of the geometry. Tetra elements are then used to fill the gap between the
hex-core mesh and the outer surface shells. Boundary layers can be introduced as well.
Examples using the Curvilinear Hex Core meshing utility: Figure 1.
