Voxel-based simulation of planar stochastic fibrous networks
voxelfiber is a morphological simulator for porous materials that can be
modeled as planar random networks. Typical examples include paper sheets
and electrospun webs. Fibers are represented by a chain of voxels in a
3D discrete spatial grid. This has the added benefit of allowing the
direct use of methods developed for the 3D imaging field. The key
property of fiber flexibility is implemented via the
mechanism originally
proposed for the KCL-PAKKA simulator.
voxelfiber requires MATLAB R2021a and above. It also requires the
Statistics and Machine Learning Toolbox. For the time being voxelfiber
will not be packaged in a toolbox. Simply download the source code and
documentation to a convenient folder.
Run the demo by typing formingdemo in the MATLAB command window.
The function forming() is used to construct the virtual material
object and method functions are applied to the object to compute
morphology features:

several minutes for large sheets with high basis weight. Help
documentation is available in the form of live scripts found under the
folder help.
