Cloud-Based Simulation of Pedestrian Urban Microclimate

Presentation of the problem and objective of the experiment

The sophistication and volume of CFD simulations required to service the Urban Physics Modelling (UPM) market are constantly increasing. These changes are driven by accelerating efforts towards digitisation and efficiency in Architecture, Engineering and Construction (AEC) and more demanding regulations for sustainability and citizen well-being, in the form of environmental legislation and guidelines.

Short description of the experiment

The Cloud-SOPHIA experiment aims to demonstrate a streamlined and highly scalable infrastructure for Urban Physics Modelling based on Open-Source Software (HELYX) and HPC. Having access to the capabilities provided by Cloud-SOPHIA will allow SME service providers to offer a broader range of industry-leading UPM solutions, reduce lead times and provide a more responsive client experience.

The experiment will consist of two stages:

  • the development and experimental verification of workflows for: a) pedestrian wind comfort and safety; b) mean wind pressure loading; c) wind-driven rain; and d) pollution dispersion
  • at-scale demonstration of the same processes on the large-scale site located in the city centre of Sofia, Bulgaria
