Arbitrary Lagrangian-eulerian (ale) Code for Plasma Simulations

چکیده
Lagrangian codes with mesh moving with the fluid suffer in many cases by mesh distortion leading to tangled mesh which in principle stops the computation as basic assumptions of the numerical method as e.g. positive volume of cells are not valid any more. Arbitrary LagrangianEulerian (ALE) method overcomes this difficulty by untangling or smoothing the mesh and conservative remapping of conserved quantities from the old mesh to the new one. After this Lagrangian computation can continue. We will report on the development of ALE code for simulation of problems from plasma physics.

Arbitrary Lagrangian Eulerian Method for Compressible Plasma Simulations
Laser plasma is modeled by Lagrangian hydrodynamical equations including heat conductivity and laser absorption. The hyperbolic part of the model is treated by Arbitrary Lagrangian Eulerian (ALE) method which avoids moving mesh distortion and parabolic heat conductivity part is treated by splitting and mimetic method. High velocity laser accelerated disc impact problems for which standard Lagra...
متن کاملDynamic Fracture Analysis Using an Uncoupled Arbitrary Lagrangian Eulerian Finite Element Formulation
This paper deals with the implementation of an efficient Arbitrary Lagrangian Eulerian (ALE) formulation for the three dimensional finite element modeling of mode I self-similar dynamic fracture process. Contrary to the remeshing technique, the presented algorithm can continuously advance the crack with the one mesh topology. The uncoupled approach is employed to treat the equations. So, each t...
متن کاملALE Simulations of Laser Driven Target Acceleration in Channel
The Arbitrary Lagrangian-Eulerian (ALE) methods are becoming very popular for simulations of laser-plasma simulations. A typical ALE method consists of three steps: a Lagrangian solver, advancing the solution to the next time step; a rezoner, improving geometrical quality of the computational mesh; and a remapper, interpolating conservatively all fluid quantities from the Lagrangian to the rezo...
متن کاملRHALE: A MMALE Shock Physics Code for Arbitrary Meshes*
This paper describes RHALE, a two and three-dimensional, multi-material, arbitrary Lagrangian-Eulerian (MMALE) shock physics code written in C++. RHALE is the successor to CTH, Sandia’s 3-D Eulerian shock physics code, and will be capable of solving problems that CTH cannot adequately address. RHALE employs a three step solution algorithm for the equations of motion: (1) a Lagrangian step capab...
متن کاملMultiMaterial ALE Methods in Unstructured Grids
Arbitrary Lagrangian Eulerian (ALE) methods have existed for several decades. However, three-dimensional multi-material arbitrary Lagrangian Eulerian (MMALE) methods for unstructured grids are relatively new. MMALE algorithms provide the framework to model sections of a simulation as either Lagrangian, ALE, or Eulerian. In addition, sections of a simulation can switch in time between mesh motio...
