Abstract


This extended abstract describes the development of an adaptive mesh refinement Eulerian hydrocode called EAGLE built around finite-volume solvers to ensure conservation of the evolved quantities and ability to handle discontinuous solutions. The application of a derivative of EAGLE, called EAGLE-Blast, to the solution of a number of simple and complex blast problems is described. This includes work to validate and verify EAGLEBlast against a range of problems of increasing complexity. These include analytically tractable 1D problems, 2D free field blast problems and more complex 3D problems. In the latter class of problems the paper describes the ability of EAGLE-Blast to reproduce two experimental studies. The paper concludes with a discussion of the use of EAGLE-Blast as the lower tier of a hierarchical modelling capability with Fast Running Engineering Models sitting in the top of the hierarchy. The full paper will be published in Defence Technology Volume 12 Issue 2.
