Laser ray tracing in a parallel arbitrary Lagrangian-Eulerian adaptive mesh refinement hydrocode

Laser ray tracing in a parallel arbitrary Lagrangian-Eulerian adaptive mesh refinement hydrocode

ALE-AMR is a new hydrocode that we are developing as a predictive modeling tool for debris and shrapnel formation in high-energy laser experiments. In this paper we present our approach to implementing laser ray tracing in ALE-AMR. We present the basic concepts of laser ray tracing and our approach to efficiently traverse the adaptive mesh hierarchy.

Implementation of adaptive mesh refinement into an Eulerian hydrocode

In this paper the implementation of an adaptive mesh refinement scheme into an existing three-dimensional Eulerian hydrocode is described. The adaptive strategy is block-based, which was required in order to leave the existing data structure intact. The focus of this work is on the development of refinement and unrefinement procedures that are conservative and preserve the locations of material...

Adaptive reconnection-based arbitrary Lagrangian Eulerian method: A-ReALE

W present a new adaptive reconnection-based arbitrary Lagrangian Eulerian: A-ReALE method. The main elements in a A-ReALE method are: An explicit Lagrangian phase on arbitrary polygonal mesh in which the solution and positions of grid nodes are updated; a rezoning phase in which a new grid is defined number of mesh cells, their location and connectivity (it is based on using Voronoi tessellatio...

AMR + + : Object - Oriented Parallel Adaptive Mesh Refinement

Adaptive mesh refinement (AMR) computations are complicated by their dynamic nature. The development of solvers for realistic applications is complicated by both the complexity of the AMR and the geometry of realistic problem domains. The additional complexity of distributed memory parallelism within such AMR applications most commonly exceeds the level of complexity that can be reasonable main...
