\chapter{Introduction}
|
|
|
|
\exo{} is the successor of the widely used finite element
|
|
(FE) data file format EXODUS [1] (henceforth referred to as EXODUS I)
|
|
developed by Mills-Curran and Flanagan. It continues the concept of a
|
|
common database for multiple application codes (mesh generators,
|
|
analysis codes, visualization software, etc.) rather than
|
|
code-specific utilities, affording flexibility and robustness for both
|
|
the application code developer and application code user. By using the
|
|
\exo{} data model, a user inherits the flexibility of using a large
|
|
array of application codes (including vendor-supplied codes) which
|
|
access this common data file directly or via translators.
|
|
|
|
The uses of the \exo{} data model include the following:
|
|
|
|
\begin{itemize}
|
|
\item problem definition -- mesh generation, specification
|
|
of locations of boundary conditions and load application, specification
|
|
of material types.
|
|
\item simulation -- model input and results output.
|
|
\item visualization -- model verification, results postprocessing,
|
|
data interrogation, and analysis tracking.
|
|
\end{itemize}
|
