SwiftBlock

Blender addon for creating blockMeshDict files for OpenFOAM's blockMesh application. Compatible with Blender 3D 2.76 ->, OpenFOAM 5.0 -> and NumPy 1.13->

New features:

  • The SwiftBlock panel has moved from the properties panel to the tools panel
  • The block structure is saved and therefore the time consuming block detection algorithm is only required when the block structure is changed
  • The blocks are listed in the SwiftBlock panel
  • Blocks can be selected, disabled and enabled interactively from the list
  • Blocks can be searched from the current mesh selection
  • Number of cells are defined instead of the maximum cell size
  • The parallel edges of an edge can be selected easily
  • The edge directions visualization
  • The new projection vertices, edges and faces to surfaces has been implemented
  • The projections are listed in the panel
  • The projections can be selected and removed from the list
  • Show/hide internal faces to make projections on them
  • The automatic snapping algorithm can also be selected
  • Extrude blocks operator which preserves internal edges and faces (ALT+E opens the extrude menu)
  • Faster block detection with Numba

How to install Blender, NumPy and SwiftBlock on Ubuntu

sudo apt install blender
sudo apt install python3-pip
pip3 install numpy
mkdir -p $HOME/.config/blender/2.xx/scripts/addons
cd $HOME/.config/blender/2.xx/scripts/addons
git clone https://github.com/flowkersma/swiftBlock/

Replace 2.xx with your Blender version. Load your OpenFOAM environment and launch Blender. In Blender open the preferences (File->User Preferences). Click on addons tab, search for SwiftBlock and enable it.

Happy meshing!
