\chapter{Summary and Conclusions}\label{c:conclude}
|
|
|
|
The \numbers\ program is a shell program which reads and stores data
|
|
from a finite element model described in the \exo\ database
|
|
format~\cite{EXODUS}. Within this shell program are several utility
|
|
routines which calculate information about the finite element model.
|
|
The utilities currently implemented in \numbers\ allow the analyst to
|
|
determine:
|
|
\begin{itemize}
|
|
\item the volume and coordinate limits of each of the materials in the model;
|
|
\item the mass properties of the model;
|
|
\item the minimum, maximum, and average element volumes for each material;
|
|
\item the volume and change in volume of a cavity;
|
|
\item the nodes or elements that are within a specified distance from a
|
|
user-defined point, line, or plane
|
|
\item an estimate of the explicit central-difference timestep for each
|
|
material;
|
|
\item the validity of contact surfaces or slidelines, that is, whether
|
|
two surfaces overlap at any point; and
|
|
\item the distance between two surfaces.
|
|
\end{itemize}
|
|
|
|
Since it is relatively easy to add a new utility to \numbers, its
|
|
capabilities should increase in the future. Utilities that may be added
|
|
in the future include the calculation of element distortion parameters
|
|
which would be useful for validating automatically generated finite
|
|
element discretizations, determination of the surface area of side sets,
|
|
and additional verification of contact surfaces. Although \numbers\ does
|
|
not currently read any of the variables, except for the displacements,
|
|
from an \exo\ file, the code is structured such that this capability
|
|
could be easily added if needed.
