Sample results of Code3. Pollutant formation. Mole fraction isopleths for: nitrogen oxide, NO (top); nitrogen dioxide, NO2 (bottom).

Implementation of the Differentially Reynolds Stress Models is pending.

Intensive work has been carried out on non-structured grids and actually a sequential prototype code (in C) to resolve the three- dimensional and transient Navier-Stokes equations is available. Other parallel C++ code is being developed, all the basic classes to contain the grids, communications, etc. have been written.

Finishing the sequential prototype for non-structured grids in C, transferring the code to the parallel C++ version, and implementing additional models in this new code, like the RANS- type models, are pending.

This is essentially what is anticipated in the project, except for the delay in the initial phase caused by the use of C++, but the result is expected to be more robust and modular.

1.4.4-Tools for the administration of the PCs Different codes in order to facilitate the installation and management of the cluster are developed. The selection and implementation of software for parallel queue management is pending.

2 Indicators of Results

Information on different indicators that can show the relevance of the results obtained up to now has been included. These indicators consider at least: staff in formation, achieved publications, technology transfer, patents, participation in international projects (especially in the EU), and collaborations with national and foreign groups.
