PDRigid Impact

Advanced impact and high-rate dynamic-behaviour modelling through an intuitive cloud-based workflow. Peridynamics naturally captures large deformations, damage, separation, and material failure — ideal for impact events where traditional FEM struggles due to mesh distortion or complex crack patterns.

High-rate impact destroys mesh-based solvers — element distortion, hourglass modes, special contact algorithms. Peridynamics is formulated on bond integrals over a non-local horizon, so massive deformation, damage, and even fragment separation happen naturally — no remeshing, no contact patches.

Five features that make peridynamic impact practical for production engineering work.

Explicit peridynamic solver for dynamic impact

Built for transient, high-rate loading:

• Explicit time integration with stable, sub-stepped dynamics
• Bond-based PD with critical-stretch failure
• Damage emerges from bond breakage — no element erosion hacks
• Captures stress waves, large deformation, and fragmentation in a single solve

Multiple rigid impactors with custom geometry

Build complex impact scenarios with arbitrary impactor shapes:

• Multiple impactors per scene, each with independent geometry
• Custom impactor shapes from STL / STEP / IGES
• Per-impactor position, velocity, mass & orientation
• Multi-impact scenarios — sequential or simultaneous
• Rigid-body impactor assumption keeps the solve focused on the deformable target

Direct CAD integration

The same CAD pipeline used across the SolidNetics stack:

• STL, STEP, IGES file support for target and impactors
• Automatic peridynamic point cloud generation for the target
• Adjustable point density for resolution control
• Multi-body parts & complex geometries

Multi-processing engine on cloud HPC

Explicit PD is parallel-friendly. SolidNetics scales it elastically:

• Multi-processing engine on high-core cloud workers
• Per-project & per-run resource scaling
• Status dashboard with run progress, compute time, queue position
• No local install, no licensing servers, no workstation needed

3D post-processing for impact visualisation

Animated 3D playback of the impact event in your browser — no local GPU required:

• Time-resolved playback of displacement, velocity & stress
• Damage maps showing crack propagation and fragmentation
• Per-timestep snapshots & export
• Color maps and scaled deformation plots

Explicit PD with sub-stepped dynamics is compute-heavy. SolidNetics elastically scales it across cloud workers — pay for the run, not the workstation.
