The current stable version of Fibez is available from Github. (https://github.com/anirban-pal/fibez)
The Fibez package has the following dependencies, with preferred versions indicated.
NLopt 2.7.1 (https://nlopt.readthedocs.io/en/latest/) GSL 2.8 (https://www.gnu.org/software/gsl/) Cuba 4.2.2 (https://feynarts.de/cuba/)
Please ensure that the above libraries are installed and the respective directories are provided in the Makefile. Installation can be performed by running "make" in the downloaded folder, which will create an executable "fibez".
The program "fibez" can be run from the command line with a single argument corresponding to a data file. The data file contains the topology of the fibrous network in terms of its control points. See sample data file (data.test) for details.
Other files can be modifed based on simulation needs. The file 'potential.h' may be modified if a different 2-body cohesive potential is needed. Currently, an LJ type potential is used. The file 'headers.h' may also be modified to change the simulation parameters.
To run the program, simply type
./fibez data.test
The program will produce 3 different outputs. The first output (log.fibez) is a time series record of potential and kinetic energies and momenta during time integration and minimization. The other 2 outputs (Output_cps.lammpstrj, Output.lammpstrj) are LAMMPS format dump files containing control point and fiber trajectories. One may use a software tool like VMD or Ovito to visualize these files.
