Auto Meshing - Internal Flow

Key Meshing Concepts#

  • Understanding mesh resolution requirements for different flow features

  • Optimizing mesh density for accuracy and computational efficiency

  • Best practices for boundary layer resolution (y+ considerations)

Mesh Quality Guidelines#

Flow360 performs best with meshes that meet these quality criteria:

  • First cell height: Appropriate y+ values based on your turbulence model

  • Growth rate: Recommended between 1.1-1.2 in boundary layers

  • Resolution: Adequate refinement in high-gradient regions

Benefits of Good Meshing#

  • Improved solution accuracy

  • Faster convergence

  • More reliable results

  • Better capture of complex flow phenomena

  • Efficient use of computational resources
