ALE3D

Arbitrary Lagrangian-Eulerian 3D and 2D Multi-Physics Code

 

ALE3DLogo

ALE3D is a 2D and 3D multi-physics numerical simulation software tool using arbitrary Lagrangian-Eulerian (ALE) techniques. The code is written to address both two-dimensional (2D) and three-dimensional (3D) problems using a hybrid finite element and finite volume formulation to model fluid and elastic-plastic response on an unstructured grid.

The ALE and mesh relaxation capability broadens the scope of applications in comparison to tools restricted to Lagrangian or

Eulerian (advection) only approaches, while maintaining accuracy and efficiency for large, multi-physics and complex geometry simulations. Beyond its foundation as a hydrodynamics and structures code, ALE3D has multi-physics capabilities that integrate various packages through an operator-splitting approach.

Additional ALE3D features include heat conduction, chemical kinetics and species diffusion, incompressible flow, wide range of material models, chemistry models, multi-phase flow, and magneto-hydrodynamics for long (implicit) to short (explicit) time-scale applications.

ALE3D4I (ALE3D For Industry) is a new version of ALE3D that allows industry and academic users to access the high-performance / high-fidelity computing capabilities of ALE3D. ALE3D4I features most of the same features and capabilities as ALE3D and is available on LLNL's massively parallel supercomputers. more >>

Environmental Report Ale3D Hydro cover.

Explicit Hydrodynamics—Enforces conservation of momentum using the Finite-Element Method. Problemscan be solved in ALE3D using the Lagrange+Remap approach. Such formulation allows the user the option to run in a variety of modes from Fully Lagrangian to Fully Eulerian.

Environmental Report Fracture and Fragmentation cover.

Fracture and Fragmentation—The Arbitrary Lagrangian-Eulerian capabilities in ALE3D provide a robust solution for high velocity impact problems while other parts of the simulation can be kept Lagrangian to provide an accurate representation of surfaces and material deformation.

Fracture and Fragmentation

In this simulation, a scored steel plate sitting against a copper buffer is impacted by a copper flyer backed by polycarbonate. The impulse launches the steel plate from the buffer, and the resulting biaxial stretching causes the plate to fracture. The fracture occurs preferentially along the score lines.

Environmental Report Ale3D Heat Transfer cover.

Heat Transfer —ALE3D is involved in process modeling for the aluminum manufacturing industry. This picture shows a simulation of several passes of a hot aluminum slab through cooled steel rollers. The plotted temperature contours show heat transfer from the slab to the rollers, which can be important to stress relaxation rates within the aluminum. The simulation also utilizes ALE3D's capabilities for slide surfaces with friction and thermal contact resistance, in addition to employing sophisticated damage evolution material models.

One of the principal forming processes for aluminum is the hot rolling of ingots into thick slabs and further rolling to form plate and sheet material of various thicknesses. Multiple passes in a reversing rolling mill of a hot slab are required to produce semi-finished aluminum plate. However, the large deformations encountered while rolling may lead to failure modes that result in loss of part or even the entire slab. The formation of defects within the plate, such as edge cracking, delamination, alligatoring (center splitting near the front and rear), and the formation of undesirable rolled end shapes, all lead to product losses.

Processing parameters could be chosen that improve product yield if the slab material response to the hot rolling process were sufficiently well understood. We have worked with a major aluminum manufacturer to develop models that:

  • Predict temperature, stress, strain, and damage evolution of slab material as it evolves through multipass rolling
  • Determine the effect of initial slab shape and rolling pass schedule on fracture and internal product integrity
  • Demonstrate the utility of a numerical model as a forming process optimization tool

It is appropriate for long time scale, low Mach number flow problems dictated by viscous effects. The model can be coupled to the heat transfer package for the computation of thermal convection problems.

Environmental Report Ale3D Magneto-Hydrodynamics cover.

Magneto-Hydrodynamics (MHD)—The MHD module solves the transient magnetic advection-diffusion equation, magnetic forces are coupled to hydrodynamics and Joule heating is coupled to heat transfer.

A simulation of a physical experiment uses large magnetic fields to compress a thin wall aluminum tube. The geometry consists of a robust steel outer tube and a 0.030-in. inner aluminum tube; the tubes are connected together at one end and connected to a header at the other end. In the physical experiment this device is connected, via 12 cables, to three 10-kV capacitor banks which are discharged simultaneously. In the ALE3D simulation, the capacitor bank and associated cables are modeled by an RLC circuit which is coupled to the Magneto Hydrodynamics (MHD) partial differential equations (PDEs). A large magnetic field exists in the space between the tubes, resulting in a large 'magnetic pressure' that will compress the inner tube.

The simulation exercises the coupling of magnetic fields with explicit hydrodynamics. The thin aluminum tube is constrained to be Lagrangian, but in the air region mesh relaxation is allowed. Since the temperature rise is small, heat transfer is ignored. In the physical experiment both strain gauges and photonic doppler velocimeters were used to measure the deformation, and ALE3D results correlated quite well with this data.


Environmental Report Ale3D Multiphase cover.

Multiphase Model—The multiphase model allows the computation of flows involving multiple dispersed materials (or phases) where each phase is treated as a continuum. It uses a cell-centered Godunov-type finite-volume scheme. Each phase possesses its own distinct velocity and state data.
