Section 1.

Introduction to the CAE data and process

management

This document serves both as a User’s Guide and as a tutorial for the ANSA Data Management system and

the ANSA Task Manager tool. Target of the document is to help the users become familiar with the ANSA

capabilities and with the functionality related to CAE data and process management. The example data

referenced here can be found in the installation directory of ANSA, under /docs/DATA_MANAGEMENT.

This guide is divided in two major sections: ANSA Data Management (section 2) and ANSA Task Manager

(section 3). Finally, the user can easily access the definitions and explanations of terms related with ANSA

Data Management and ANSA Task Manager through the index provided at the end.

In the ANSA Data Management section the user is guided through the build-up of an ANSA Data Management

Root directory in a stepwise way, via the ANSA Data Management functionality. The major aspects of ANSA

Data Management are explained and the advantages of working with this data management system are

explored.

In the ANSA Task Manager section the features of ANSA Task Manager are explained and the user is guided

through the creation and execution of custom processes. The possibility of using standard ANSA functionality

from within ANSA Task Manager is discussed and emphasis is given on the exploitation of existing, manually

built models’ data for use through the Task Manager. Finally, the user can easily access the definition and

description of terms related with ANSA Data Management and ANSA Task Manager through the index

provided in the last pages.

The DM_DEMO example directory is built for a door closure sub-assembly. Such an example enables the

demonstration of most of the capabilities of ANSA Data Management in conjunction with ANSA Task

Manager, while at the same time it can be considered as an easy to handle example. The directory

additionally contains libraries and templates.

The example files are packed in the DATA_MANAGEMENT.tar.gz and DM_DEMO.tar.gz files. These files

contain:

DM_DEMO directory: This is a sample, fully functional ANSA Data Management root directory

DATA_MANAGEMENT directory: This directory contains all the data needed for the build-up of an ANSA

Data Management root directory

Section 2.

ANSA Data Management

The first question that we should probably answer to all users is: What is the ANSA Data Management?

Thus, in short term:

ANSA Data Management (ANSA DM) is a centralized data management system, used to collect and store in

a structured and hierarchical form all engineering data that are used during the development process of a

vehicle simulation model.

Under ANSA DM, all engineering data are stored in the same physical location. This location is made known

to ANSA, so that all communication related to the storage and retrieval of engineering data and their updates

is managed automatically.

The next question that arises is: What can these engineering data be?
