Simulation of the dynamics of an elastic filament with tangential self-propulsion used in the research article Buckling instabilities and spatio-temporal dynamics of active elastic filaments, J. R. Soc. Interface 17: 20190794. by Yaouen Fily, Priya Subramanian, Tobias M. Schneider, Raghunath Chelakkot, and Arvind Gopinath.
-
Numerical solution of the partial differential equations for the dynamics of an elastic filament with tangential self propulsions with various boundary conditions (free end, fixed end, clamped end, point viscous load).
-
Live preview of filament motion.
Only tested in linux. Requires boost (filesystem, system, iostreams) and trilinos (epetra, amesos, teuchos) libraries. On an ubuntu-like system you can install those with something like:
> sudo apt install libboost-filesystem-dev libboost-system-dev libboost-iostreams-dev libtrilinos-epetra-dev libtrilinos-amesos-dev libtrilinos-teuchos-dev
The live preview feature requires gnuplot.
Once dependencies are installed, compile with make. You may need to edit the Makefile to reflect where you installed the dependencies.
After compilation, run
> execute parameters.txt
To change parameter values, edit parameters.txt and run again.
