1.3.1 Introduction

1.3.2 Creating Connectors on the Hull

1.4 Hexa Blade

Highlight Steps:

  1. blade surface mesh (domain) domain on database, cluster on tip, root, LE, TE
  2. Blade domain normal extrude
  3. Periodic Boundary domain mesh
  4. Split block
  5. add connector, assemble shroud and hub domains
  6. Normal extrude >> blade Boundary extrusion
  7. Elliptical solver >> smoothing mesh

1.13 unstructured 3D block from domain(2d mesh)

Create/assemble special/block Select one face and then Select/select all adjacent (C+S+A) Select all faces composing the block(3d mesh) initialize >How to Create an Unstructured Block with an Internal Face

1.13.1 pick a domain to add to the first face. the first face should be the outer face and must be a closed face
