Main Features

🎯 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

Installation

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.

Usage

To run the dynamic tensile test simulation, just 7 lines of code are needed:

julia
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:

bash
mpiexec -n 6 julia --project path/to/script.jl

Please take a look at the how-to guide on MPI for more details.
