Abstract :
ALEGRA is one of the principal computer codes being used at Sandia National Laboratories for simulating the dynamic material response of complex configurations. It solves coupled physics problems in two or three spatial dimensions using Lagrangian, Eulerian, and/or ALE (Arbitrary Lagrangian Eulerian) coordinates. The code runs on massively parallel computers, and contains a large variety of physics options including hydrodynamics, MHD with external circuit coupling, radiation transport, thermal conduction, and dual ion and electron temperatures. Applications simulated to-date include exploding Z-pinch wires, imploding Z-pinch plasma sheaths and wire arrays, isentropic compression and flyer plate experiments, radiation-driven jetting experiments, and debris effects on partitioned pipes. We present several calculations performed with the MHD, radiation, and coupled-physics modeling capabilities available within the ALEGRA framework.
