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:
- porosity, by function
porosity() - sheet thickness, by function
thickness() - relative bonded area, by function
rba() - number of contacts between fibers, by function
numcrossings() - number of fibers covering a point, by function
coverage()
3D visualization is done using function vis_sheet(). This can take
several minutes for large sheets with high basis weight. Help
documentation is available in the form of live scripts found under the
folder help.
A basic description of voxelfiber can be found in Coding a Simulation Model of the 3D Structure of Paper. Please cite this paper if you use voxelfiber.
