HiDALGO2 D5.8 Implementation Report on Pilot Applications

D5.8 presents the implementation advances of the five HiDALGO2 pilot applications and their couplings at M46. Continuing D5.6 and D5.7, it explains how research developments have been incorporated into software and HPC workflows. The main advances concern physical models, application data, and the connection of simulation with analysis and visualisation.

The Urban Air Project has extended its capabilities for simulating urban airflow and pollutant transport. Developments in physical modelling and the preparation of urban geometry, vegetation and emissions support applications addressing air quality and wind comfort.

The Urban Building Model has extended the preparation and representation of buildings, solar exposure and building physics. Scenario and ensemble workflows connect these models with building data and result analysis, supporting studies of energy use, indoor conditions and urban climate.

The Renewable Energy Sources pilot has extended wind and photovoltaic forecasting and the workflows used to prepare and execute these applications. The integration of meteorological simulation and data-driven prediction supports the assessment of renewable electricity production.

The Wildfires pilot has developed capabilities for landscape fire simulation and for representing fire behaviour near buildings. Advances in vegetation preparation, simulation and visualisation connect environmental data with the analysis of fire and smoke scenarios.

The Material Transport in Water pilot has extended particle-laden flow simulation to include heat exchange between moving particles and the surrounding fluid. CPU and GPU implementations, together with ensemble execution and analysis tools, support the investigation of coupled transport processes.

Across the pilots, application workflows connect data preparation, numerical models and computing resources. Build and testing arrangements, deployment mechanisms and result processing support their use. The technical summaries give a common description of the software components and interfaces.

Coupling work connects complementary models through meteorological, thermal and environmental data exchanges. File-based workflows and direct solver interfaces provide different ways to study interactions across application domains. The coupling section documents these mechanisms and their application examples.

These developments broaden the questions that the pilots can address and support further integration and reuse. D5.2, currently in preparation, will draw on this implementation work to assess the final synergies and benefits of integrated models, software and hardware.
