Reply To: Turbogrid generates poly or Tetra mesh?

[Rob Blumenthal]

For the main flow passage, TurboGrid creates quadrilateral elements on 2D surfaces of revolution at different span fractions using a mesh topology based on the type of blading. These layers are used to interpolate the mesh in the span-wise direction, creating 3D hexahedral elements.
For secondary flow passages, TurboGrid creates a 2D mesh composed of quadrilateral elements (inflation layers) and tetrahedral elements (outside the inflation region). These elements are extruded in the circumferential direction to generate 3D hexahedral and prismatic elements.
