Key Use Cases
What is ANSYS AUTODYN
The engineering hydrocode for extreme dynamic events
ANSYS AUTODYN is an explicit hydrocode — a specialized solver for high-rate dynamic events where pressures reach GPa, materials undergo shock compression, phase changes, and fragmentation in microseconds. It was originally developed at Swansea University and Century Dynamics for nuclear weapons effects analysis, and has since become the standard tool for defence engineering, blast protection design, explosive mining, and hypervelocity impact research.
AUTODYN differs from general explicit FEA (LS-DYNA) in its deeper specialization for detonation and blast physics: a built-in Eulerian solver calibrated for high-explosive detonation, the most comprehensive EOS library in the industry, and multiple fragmentation models for realistic debris prediction. CADFEM Ukraine provides official AUTODYN licenses, English-language training, and blast simulation consulting in Ukraine.
Multi-solver model in one file
Lagrangian FEM for structures, Eulerian/ALE for explosives and air, SPH for hypervelocity and fragmentation — all interact in a single AUTODYN model without coupling files or separate codes. FSI contact transfers blast pressure to structure automatically at every time step.
Comprehensive EOS library
JWL (Jones-Wilkins-Lee) EOS for explosives (TNT, C4, RDX, PETN, ANFO, Comp B) with experimentally calibrated parameters; Mie-Grüneisen for metals under shock; P-alpha for porous materials; TILLotson for geological materials. Built-in Hugoniot database for hundreds of materials.
Advanced material failure models
Johnson-Cook strength and fracture (strain-rate dependent), Grady-Kipp statistical spall fracture for brittle fragmentation, CEB (Comité Euro-International du Béton) for reinforced concrete, EPIC for ceramics, and user-defined failure criteria via subroutines.
Direct ANSYS Mechanical coupling
Post-blast structural analysis workflow: AUTODYN computes the detonation and blast wave loading (microseconds to milliseconds); deformed geometry and stress state are imported into ANSYS Mechanical for subsequent long-duration structural analysis (residual capacity, repair design).

Numerical Methods
Solvers in ANSYS AUTODYN
AUTODYN combines multiple solvers in one model — each physics region uses the optimal numerical method for its material state
Lagrange

SPH
Smooth Particle Hydrodynamics

Multi-solver FSI
Automatic contact-based coupling between Lagrange, Euler, ALE, and SPH meshes in one model. Blast pressure from ALE/Euler automatically loads the Lagrange structure.

AUTODYN vs LS-DYNA
What is the difference between ANSYS AUTODYN and ANSYS LS-DYNA?
Both are explicit nonlinear codes, but with different strengths. AUTODYN: historically specialized for blast and detonics — richer EOS database for explosives, built-in Euler solver for detonation, more fragmentation models (Grady-Kipp). LS-DYNA: more general — better for crashworthiness, sheet metal forming, and large-scale HPC. For detonation physics and blast-dominated problems: AUTODYN is often preferred. For crash and forming: LS-DYNA. Both are available from CADFEM Ukraine.
License
What ANSYS license is required for AUTODYN?
ANSYS AUTODYN is included in ANSYS Mechanical Enterprise. It is also available as a standalone license. For coupled AUTODYN + ANSYS Mechanical post-blast analysis, ANSYS Mechanical Enterprise is required. Contact CADFEM Ukraine for the optimal license configuration for your application.

+38 (050) 454-37-54What is ANSYS AUTODYN and what makes it different from general FEA?
+
ANSYS AUTODYN is an explicit hydrocode — a specialized solver for extreme high-rate dynamic events where pressures reach GPa and materials undergo phase changes, fracture, and fragmentation in microseconds. Unlike general FEA (ANSYS Mechanical), AUTODYN implements: Equations of State (EOS) describing material behaviour under shock loading; multi-solver architecture (Lagrange, Euler, ALE, SPH) in a single model; high-explosive initiation and detonation physics (JWL EOS, CJ state); and statistical fragmentation models (Grady-Kipp). It is the tool of choice for defence engineering, blast protection design, and detonics research.
What is the difference between ANSYS AUTODYN and ANSYS LS-DYNA for blast analysis?
+
Both codes solve explicit nonlinear dynamics, but AUTODYN has deeper specialization in blast and detonics: built-in Eulerian solver specifically calibrated for high-explosive detonation (JWL EOS database for 30+ explosives), Grady-Kipp fragmentation model, CONWEP analytical blast model for rapid open-space analysis. LS-DYNA has the ALE solver and CONWEP as well, but the explosive EOS library is less extensive, and LS-DYNA's strength is in larger-scale HPC problems (crash, forming). For detailed detonation physics and shaped charge design — AUTODYN is typically preferred.
What Equations of State (EOS) are available in ANSYS AUTODYN?
+
AUTODYN includes an extensive EOS library: JWL (Jones-Wilkins-Lee) for high explosives — TNT, C4, RDX, PETN, ANFO, Composition B, with experimentally calibrated A, B, R1, R2, ω parameters; Mie-Grüneisen (linear Us-Up Hugoniot) for metals (steel, aluminium, copper, titanium) — Hugoniot data for 200+ materials; P-alpha for porous materials (sand, soil, concrete) and equation of state of porous media under shock compaction; TILLotson for geological materials and asteroid/meteorite impact; Ideal Gas for air and detonation products. The built-in material library contains over 400 validated material datasets.
How does ANSYS AUTODYN model a shaped charge (HEAT warhead)?
+
A shaped charge model in AUTODYN uses: Lagrangian or ALE mesh for the copper or steel liner; JWL EOS for the high explosive charge behind the liner; Eulerian or SPH region for the jet formation region. Detonation initiates at the apex, the detonation wave collapses the liner, and the metal liner forms a high-velocity jet (tip velocity >8 km/s). SPH is preferred for the jet-armour interaction phase where the jet undergoes extreme elongation and particulation. The simulation predicts jet velocity profile, penetration depth, and perforation diameter as a function of standoff distance.
How does AUTODYN model underwater explosion (UNDEX)?
+
UNDEX modelling in AUTODYN uses ALE (Arbitrary Lagrangian-Eulerian): water and explosive are modelled as Eulerian materials; the ship hull structure is Lagrangian; FSI coupling transfers pressure from the shock wave to the hull at every time step. The simulation captures: initial shock wave (near-field high pressure), bubble formation and pulsation (secondary pressure loading), and hull response (plastic deformation, rupture). This is the standard approach for naval ship survivability assessment and underwater mine clearance charge design.
Does CADFEM Ukraine provide AUTODYN support in English for defence contractors?
+
Yes. CADFEM Ukraine provides all AUTODYN services in English: official license procurement (including for export-oriented Ukrainian defence companies), technical support, blast and ballistics simulation consulting with English deliverables, training courses in English, and secure installation support. We understand the sensitivity of defence-related work and can accommodate confidentiality requirements in our consulting engagements.
