Calibrated reduced order models for rectangular floor-plan and CFD simulations with recalibrated turbulence models for general building topologies
Target building with surrounding conditions, up to neighborhood scales. Input geometry compatible with CityGML and CityJSON formats
To evaluate natural ventilation in buildings, the input and the output formats are also compatible with EnergyPlus software (E+) to perform airflow network analysis
Auto-recognition of windows and doors. Specific Cp data computed. E+ objects generated and exported
To represent architectural elements of interest like balconies, overhangs, shadings, among others
Surface and volumetric fields exported in VTK format
User must upload the building geometry file and the configuration of the ABL wind profile. The geometry should be split in as many surfaces as the level of detail for pressure coefficients be required.
Automatic procedures generate the virtual wind-tunnel, mesh the domain and configurate the CFD simulation following the COST actions guidelines.
RANS equations are solved using a finite-volume based steady-state solver. Turbulence is modeled using standard or recalibrated RANS models for specific ABL applications. One simulation per wind angle is performed in our clusters.
Surface-averaged and point Cp data are computed on each selected surface. Surface and volumetric field data are also generated.
Results data is returned to the user. It includes a .csv table of Cp per surface and wind angle, .idf file updated (if required), and .vtk files for specific post-processing and other statistics.
