Best Practices and Contemenations

  • Use high- kualitate, cleared meshes near blade surface.
  • Apply acuate ate boundary conditions for te operating ocement.
  • Perform mesh independen studigo to ensure resulty stabil.
  • Model Validatte with experiental data whenever possible.
  • Dokument all assumps and settings for reproducibility.
