We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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.
