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
