Finite Element Solver for Fission Dynamics
Abstract
FELIX is a physics computer code used to model fission fragment mass distributions in a fully quantummechanical, misroscopic framework that only relies on our current knowledge of nuclear forces. It is an implementation of the timedependent generator coordinate method (TDGCM), which simulates the dynamics of a collective quantum wavepacket assuming the motion is adiabatic. In typical applications of the TDGCM, the nuclear collective wavepacket is obtained as a superposition of wavefunctions obtained by solving the HartreeFockBogoliubov equations of nuclear density functional theory (DFT). The program calculates at each time step the coefficients of that superposition.

FELIX is a physics computer code used to model fission fragment mass distributions in a fully quantummechanical, microscopic framework that only relies on our current knowledge of nuclear forces [1]. It is an implementation of the timedependent generator coordinate method (TDGCM), which simulates the dynamics of a collective quantum wavepacket assuming the motion is adiabatic. In typical applications of the TDFCM, the nuclear collective wavepacket is obtained as a superposition of wavefunctions obtained by solving the HartreeFockBogoliubov equations of nuclear density functional theory (DFT). The program calculates at each time step the coefficients of that superposition.

An AMR capable finite element diffusion solver for ALE hydrocodes [An AMR capable diffusion solver for ALEAMR]
Here, we present a novel method for the solution of the diffusion equation on a composite AMR mesh. This approach is suitable for including diffusion based physics modules to hydrocodes that support ALE and AMR capabilities. To illustrate, we proffer our implementations of diffusion based radiation transport and heat conduction in a hydrocode called ALEAMR. Numerical experiments conducted with the diffusion solver and associated physics packages yield 2nd order convergence in the L _{2} norm. 
Solution of problems with material nonlinearities with a coupled finite element/boundary element scheme using an iterative solver. Yucca Mountain Site Characterization Project
The prediction of stresses and displacements around tunnels buried deep within the earth is an important class of geomechanics problems. The material behavior immediately surrounding the tunnel is typically nonlinear. The surrounding mass, even if it is nonlinear, can usually be characterized by a simple linear elastic model. The finite element method is best suited for modeling nonlinear materials of limited volume, while the boundary element method is well suited for modeling large volumes of linear elastic material. A computational scheme that couples the finite element and boundary element methods would seem particularly useful for geomechanics problems. A variety ofmore » 
Binary tree eigen solver in finite element analysis
This paper presents a transputerbased binary tree eigensolver for the solution of the generalized eigenproblem in linear elastic finite element analysis. The algorithm is based on the method of recursive doubling, which parallel implementation of a number of associative operations on an arbitrary set having N elements is of the order of o(log2N), compared to (N1) steps if implemented sequentially. The hardware used in the implementation of the binary tree consists of 32 transputers. The algorithm is written in OCCAM which is a highlevel language developed with the transputers to address parallel programming constructs and to provide the communications betweenmore »
