A high-level Julia package for parallel peridynamics simulations
- 🎯 Dynamic and quasi-static analysis
- 🪨 Multiple peridynamics formulations and material models
- 🎳 Multibody contact simulations
- 🤓 User friendly API that captures many errors before submitting simulations
- 🚀 Enhanced HPC capabilities with MPI or multithreading
Peridynamics.jl
is a registered Julia package, so you can install it by just typing
add Peridynamics
in the julia package manager. Please take a look at the documentation for more details on the installation.

To run the dynamic tensile test simulation shown above, just 7 lines of code are needed:
body = Body(BBMaterial(), "TensileTestMesh.inp")
material!(body; horizon=0.01, rho=2700, E=70e9, Gc=100)
velocity_bc!(t -> -0.6, body, :bottom, 1)
velocity_bc!(t -> 0.6, body, :top, 1)
vv = VelocityVerlet(steps=500)
job = Job(body, vv; path="results/tension_dynamic")
submit(job)
Take a look at the tutorial of the tensile test for more details on this example.
If you want to run this example with multithreading, just start Julia with more than 1 thread. To use MPI, you can create a script containing the same code without changes and run it with:
mpiexec -n 6 julia --project path/to/script.jl
Please take a look at the how-to guide on MPI for more details.
