The verification example describes the steady-state flow around a high-rise building in city blocks (scaled model). The example is given by the Architectural Institute of Japan (AIJ). Chosen results (velocity magnitude) are compared with the measured values.
The verification example describes wind loads in several wind directions on a model of a group of buildings. The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel. 

A sphere is subjected to uniform flow of viscous fluid. The velocity of the fluid is considered at infinity. The goal is to determine the drag force. The parameters of the problem are set so that the Reynolds number is small and the radius of the sphere is also small, thus the theoretical solution can be reached - Stokes flow (G. G. Stokes 1851).

The verification example describes pressure loads on the walls of buildings in tandem arrangment located at ground level. Buildings are simplified to rectangular objects and scaled down while maintaining elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by experiment. Chosen results (pressure coefficient Cp) are compared with the measured values.

The verification example describes the steady-state flow around an isolated building (scaled model).The example is given by the Architectural Institute of Japan (AIJ). Chosen results (velocity magnitude) are comparedwith the measured values.

This verification example compares wind load calculations on a flat roof building by means of the ASCE 7-16 standard and by means of CFD simulation in RWIND Simulation. The building is defined according to the sketch and the inflow velocity profile taken from the ASCE 7-16 standard.

This verification example compares wind load calculations on a duopitch roof building by means of the ASCE 7-16 standard and by means of CFD simulation in RWIND Simulation. The building is defined according to the sketch and the inflow velocity profile taken from the ASCE 7-16 standard.

The verification example compares wind load calculation on the building with duopitch roof by means of the standardEN 1991-1-4 and by means of CFD simulation in RWIND Simulation. The building is defined according to the sketch andthe inflow velocity profile is taken according the standard EN 1991-1-4.
