1 Introduction

SnappyHexMesh GUI add-on for Blender turns Blender into a GUI for preparing case files for SnappyHexMesh. The aim is to

  • Ease the workflow for updating, modifying and exporting 3D surface meshes to OpenFOAM.
  • Allow definition of most common SnappyHexMesh settings via Blender GUI, to reduce need for manual writing of OpenFOAM dictionary definitions.
  • Require minimal Blender skills. Geometry can be modelled in any 3D modelling / CAD program which exports a surface mesh format that can be imported to Blender, such as STL or Wavefront OBJ. Add-on is operated via panels in Blender's GUI.

The creation of OpenFOAM dictionary files is based on string replacements using template files located in the add-on's skel directory. The add-on is supported on latest Blender LTS version.

Usage is shown in the video tutorial series Blender for OpenFOAM users.
