BFDS stands out in the blender_extensions library as the successor to BlenderFDS, carrying a project first shown at the Blender Conference 2009 into current Blender releases.
BFDS fire simulations is a Blender add-on built for creating and managing NIST Fire Dynamics Simulator (FDS) models. FDS is an open source large-eddy simulation (LES) code for low-speed flows, with an emphasis on smoke and heat transport from fires. Rather than entering complex geometry by hand, BFDS lets you use Blender's 3D tools to build and edit FDS entities directly in a familiar environment.
The add-on is aimed at fire safety engineers, researchers, and students, and keeps attention on the simulation itself instead of the geometry setup. It is the successor to the BlenderFDS project, a community-driven initiative first presented at the Blender Conference 2009 and developed continuously since.
BFDS can import and export FDS files from and to disk, and it can display geographic positions and convert coordinates. It works with Blender 4.5 LTS and newer, and is released under the GNU General Public License v3.0 or later.
BFDS fire simulations is best for fire safety engineers, researchers, and students building NIST FDS fire simulations inside Blender.
BFDS fire simulations is completely free to download and use.
BFDS fire simulations is compatible with Blender 4.5 LTS and newer, so it targets current long-term-support releases rather than older versions. The add-on brings NIST Fire Dynamics Simulator modelling into Blender, letting you use its 3D tools to build and edit FDS entities in a familiar environment. If you run a Blender version below 4.5, you would need to update before installing. For version details and the latest builds, check the developer's page at github.com/firetools/bfds.
BFDS fire simulations can be added by dragging and dropping it into Blender, or by downloading the file and using Install from Disk. Both routes place the add-on inside Blender so you can start creating and managing NIST FDS models. Because it requests file permissions to import and export FDS files, and network permissions to display geographic positions and convert coordinates, review those when enabling it. Full instructions are on the developer's page at github.com/firetools/bfds.
BFDS fire simulations is listed as free in this catalog and is released under the GNU General Public License v3.0 or later, an open source license. That governs how you may use, modify, and share the add-on. NIST FDS, the simulator BFDS builds models for, is itself open source large-eddy simulation code. For current licensing terms and any updates, check the developer's page at github.com/firetools/bfds.
BFDS fire simulations imports and exports FDS files from and to disk, which is how it moves models in and out of the NIST Fire Dynamics Simulator workflow. It also displays geographic positions and converts coordinates through network access. You build and edit the underlying FDS entities using Blender's own 3D tools before exporting. For more detail on supported files and workflow, see the developer's page at github.com/firetools/bfds.
