Key Use Cases
What is ANSYS LS-DYNA
The global standard for nonlinear explicit dynamics
ANSYS LS-DYNA was developed at Lawrence Livermore National Laboratory in the 1970s and has been the world's leading explicit nonlinear FEA code for five decades. It is the mandatory tool for automotive crash certification (NCAP, FMVSS), aviation bird strike certification (CS-25/FAR-25), and defense ballistic and blast analysis.
Unlike implicit solvers, LS-DYNA advances the solution in tiny time steps without inverting a global stiffness matrix — making it robust for events that last microseconds to milliseconds with extreme mesh distortions, material failure, and thousands of simultaneous contact interactions. CADFEM Ukraine provides official LS-DYNA licenses and English-speaking simulation support in Ukraine.
Explicit time integration — no convergence issues
LS-DYNA advances the solution in tiny time steps (microseconds) without solving a global stiffness matrix. This means no convergence problems even with extreme deformations, material failure, and complex contact between thousands of bodies.
200+ material models
Johnson-Cook metals with failure, rubber and foam (Ogden, Mooney-Rivlin), concrete (MAT_CSCM, MAT_159), explosive JWL, biological tissues, composites — the most complete material library in explicit dynamics.
SPH and meshfree methods
Smoothed Particle Hydrodynamics (SPH) handles extreme deformations where FEM elements would distort: bird strike (bird modelled as viscous fluid), explosive fragmentation, hypervelocity impact, fluid sloshing.
MPP parallel scaling for HPC
LS-DYNA MPP (Massively Parallel Processing) scales linearly to thousands of CPU cores on HPC clusters. A full-vehicle crash model (1M+ elements) runs in hours instead of days. CADFEM Ukraine provides HPC configuration support.

Numerical Methods
Computational methods in ANSYS LS-DYNA
LS-DYNA offers multiple numerical methods in one model — each optimized for its class of physics
Lagrangian FEM
Lagrangian FEM
The standard explicit FEM formulation where the mesh moves with the material. Used for solid structures, armor, vehicle bodies, and composite parts. Highly accurate for moderate to large deformations.
✓ Crash, armor, sheet metal forming
ALE
Arbitrary Lagrangian-Eulerian
Hybrid method: Eulerian mesh for fluids and explosives (air, water, TNT), Lagrangian mesh for the structure. FSI coupling transfers blast pressure to the structure automatically at every time step.

Licensing & Procurement
ANSYS LS-DYNA in Ukraine: license, price, SMP vs MPP
Where to buy
How to get an official ANSYS LS-DYNA license in Ukraine?
CADFEM Ukraine is the sole authorized ANSYS Channel Partner in Ukraine. We provide official LS-DYNA licenses — SMP and MPP — with full contractual support, English-speaking engineering team, training, and simulation consulting. Contact us for a commercial proposal.
Pricing
How much does ANSYS LS-DYNA cost?
Pricing depends on license type (lease or perpetual), version (SMP for single node vs MPP for HPC clusters), and number of CPU cores licensed. Submit a request — we prepare individual quotes based on your simulation scale and budget.
SMP vs MPP
What is the difference between LS-DYNA SMP and MPP?
LS-DYNA SMP (Shared Memory Parallel) runs on a single multi-core workstation using shared memory — suitable for up to ~32 cores. LS-DYNA MPP (Massively Parallel Processing) distributes the model across multiple nodes using MPI — scales to thousands of cores on HPC clusters. For full-vehicle crash or large defense models, MPP is recommended.

+38 (050) 454-37-54What is ANSYS LS-DYNA and what problems does it solve?
+
ANSYS LS-DYNA is the world's leading explicit nonlinear FEA solver — originally developed at Lawrence Livermore National Laboratory. It is optimized for short-duration, high-nonlinearity dynamic events: crash tests, blast loading, ballistic penetration, bird strike, metal forming, and hypervelocity impact. Unlike implicit solvers (ANSYS Mechanical), LS-DYNA uses explicit time integration — no global stiffness matrix inversion — which makes it robust for extreme deformations, material failure, and thousands of contact interactions that implicit solvers cannot handle.
What is the difference between ANSYS LS-DYNA and ANSYS Mechanical?
+
ANSYS Mechanical uses implicit time integration — excellent for static analysis, vibration, and slow quasi-static nonlinear problems. It struggles with large deformations and contact-heavy models that cause convergence failures. ANSYS LS-DYNA uses explicit time integration — designed for events lasting microseconds to milliseconds with extreme deformations, material failure, and complex contact. Rule of thumb: if the event lasts less than 1 second and involves impact, crash, blast, or large plastic deformation — use LS-DYNA.
What is SPH in LS-DYNA and when should I use it?
+
SPH (Smoothed Particle Hydrodynamics) is a mesh-free particle method where material is represented by particles rather than elements. It handles cases where FEM elements would distort and fail. Key applications: bird strike (the bird is modelled as a viscous fluid particle cloud — at 200 m/s impact, the bird behaves hydrodynamically); explosive fragmentation (particles fly apart naturally); hypervelocity penetration of armor (shaped charge jet). SPH is used when extreme local deformation makes standard FEM unreliable.
How does LS-DYNA model blast loading on a structure?
+
Two methods: ALE (Arbitrary Lagrangian-Eulerian) — the explosive and air are modelled as Eulerian materials, the structure as Lagrangian; the blast pressure wave is automatically transferred to the structure through FSI coupling. More accurate but computationally expensive. CONWEP — analytical blast model based on the Kingery-Bulmash empirical database; pressure is applied directly to the structure surface without modelling the air. Faster; suitable for open-space blast scenarios.
Can ANSYS LS-DYNA model CFRP composite failure for UAV structures?
+
Yes. LS-DYNA has dedicated composite material models: MAT_054/055 (Chang-Chang failure criteria), MAT_058 (Laminated Composite Fabric with tabulated failure), MAT_262 (Unidirectional composite with delamination via CZM). Layered shell elements capture ply-by-ply stress states. This is used for UAV airframe crashworthiness, bird strike on composite wings, and blast response of CFRP armor panels.
Does CADFEM Ukraine support LS-DYNA in English for defense contractors?
+
Yes. CADFEM Ukraine provides full English-language LS-DYNA services: official license procurement, technical support, crash and impact simulation consulting, HPC cluster setup, and training courses. We actively support Ukrainian defense and aerospace engineering organizations working on UAV structural analysis, ballistic protection, and blast-resistant vehicle design.
