[Turbofan]

Hello everyone,

For my thesis I am working on a 3D mesh for a turbomachinery blade. Inspired by the tutorial "Multiblock Structured Meshing for a High Stagger Angle Axial Rotor" I was able to complete a preliminary mesh. This is essentially composed by 9 main blocks following an H-O-H structure, where the boundary layer was directly extruded from the blade and then splitted into various sub-blocks. Here are some images of the mesh structure (Hub, Shroud, Entire Mesh)

Although the result is good, I tried to improve it by using the elliptic solver on all the blocks using the Floating type as boundary condition. However this does not allow the connectors created on hub and shroud to move, leading to an high skewness. So I ask you, is it possible to use the elliptic solver with floating conditions and allow some faces to move? If so, how? Could anyone else suggest me an alternative strategy to create a mesh for a high twisted blade?


Thanks in advance!
