Abstract:

This document contains the descriptions, algorithms, user information and listings of the parallel Fortran90/MPI versions of the suite of programs found in NIST-IR 6269, Finite Element and Finite Difference Programs for Computing the Linear Electric and Elastic Properties of Digital Images fo Random Materials. These programs use 3-D digital image data on random materials as input and then calculate the effective properties of the random material when subjected to applied fields (for example, mechanical/thermal stresses and AC/DC electric fields). The purpose behind this undertaking is to execute these programs in a parallel computing environment (for example, Linux clusters), so as to decrease real-time execution, increase the potential problem size, and ncrease digital resolution/problem accuracy.
