for colocation. For the users PAGEIN has integrated on top of wide-area networks,
applications, and tools for supercomputing, visualization, and multimedia. It has
demonstrated the viability of such combined technologies in CFD to be exploited
on a European scale by aerospace actors.
The Live Code Learning Multimedia System (LCLMS) [

] was the IWT
founded project, in which the database and network aspects for multimedia
datasets were researched. This project strongly influenced the author's own
research toward distributed and collaborative environments for engineering
applications based on low-cost PC-platforms. LCLMS provided the basic tech-
nology upon which QFView was designed.
1.2.1 Alice: QFView Toward the Transparent Visualization
of Numerical and Experimental Data Sets
The development of the Quantitative Flow Field Visualization (QFView) system
[
45
] was made in the ESPRIT Project 28168 ALICE. QFView is a distributed
software environment that integrates EFD and CFD data processing, including
flow field mappings with flow field visualization, see Fig.
1.15
. QFView was
devised to support a unified treatment of data while providing for:
• the validation of results from experimental and numerical systems,
• the archival and retrieval of data from unified (experimental and numerical)
flow field database.
Based on proven Internet and World Wide Web (WWW) standard technologies,
QFView provides an integrated information system for fluid dynamics researchers.
QFView is a web-based archival, analysis and visualization system, which enables
the manipulation and extraction of data resulting from laboratory measurements or
computational simulations. The system is suited for combining experimental and
computational activities in a single operational context. This results in an increase of
productivity, since the system facilitates for the exchange of information between
investigators who conduct the same or similar simulations/experiments in different
geographical locations, can be conducted in collaboration or independently.
The development of QFView in the ESPRIT-IV ''ALICE'' project (EP-28168)
extended the author's research toward using the World Wide Web for designing
and building up distributed, collaborative scientific environments [
45
,
46
]. QFView
was developed in a web-oriented client-server architecture (e.g., Java, JDBC)
which allowed openness and modularity, as well as improved flexibility and
integration of the visualization components (current and future). A core element
was the creation of a central database where very large datasets were imported,
classified, and stored for reuse. The distributed nature of QFView allows the user to
extract, visualize, and compare data from the central database using World Wide
Web access. QFView integrates EFD and CFD data processing (e.g., flow field
mappings with flow field visualization).
