PlotDrag
Drag is the force acting on the object in the flow direction. This is a positive force that "pushes" the object along with the flow.

The plot in this section show the total aerodynamic forces (N) acting on the specified buildings over time (s). Without building of interest, the force on the entire uploaded model is calculated. The time period corresponds to the time for the wind to pass over the building complex from one end to the other.
Drag
PlotSide force
The side force is perpendicular to the inflow direction. This force will "push" the object to the side.

The plot in this section show the total aerodynamic forces (N) acting on the specified buildings over time (s). Without building of interest, the force on the entire uploaded model is calculated. The time period corresponds to the time for the wind to pass over the building complex from one end to the other.
Side force
PlotVertical force
The vertical force acts on the direction of gravity and can be either positive or negative. A negative force "pushes" the object down towards the ground.

Vertical force
PlotSurface load
This plo shows the magnitude of the force acting on the object at different heights. Since this is a magnitude plot, it doesn't show the direction. But it's probable that most of the force is in line with the wind direction.

Time lapse
This section shows the wind load (pressure) on the buildings with the help of a time lapse movie. A time lapse movie shows the wind load in different locations, changing over time.

The colors indicate if the pressure is reduced or increased relative to the pressure given at the outflow. Blue colors indicate that the pressure is reduced. Red colors indicate that the pressure is increased.

Average
This section shows the wind load (pressure). Each image is based on the average wind load, and is visualized for a full rotation, divided in steps of 10 degrees.

The colors indicate if the pressure is reduced or increased relative to the pressure given at the outflow. Blue colors indicate that the pressure is reduced. Red colors indicate that the pressure is increased.
Time lapse
This section shows the wind flow (velocity) around the buildings with the help of a time lapse movie. A time lapse movie shows the wind flow in different locations, changing over time. For the side view, the camera is placed orthogonally (90°) to the wind direction and is focused on the building of interest.

Apart from wind effects, it is also possible to see a pressure field around 0. This pressure field is used to detect flow separation. Flow separation can often result in increased drag, particularly pressure drag.

Time lapse
This section shows the wind flow (velocity) around the buildings with the help of a time lapse movie. A time lapse movie shows the wind flow in different locations, changing over time. For the top view, the camera is placed orthogonally (90°) to the bottom and is focused on the whole model.

You can use this view to find different wind effects, and see how they vary over time. Wind effect can be used to initiate passive cooling, or to disperse pollutants, but can be also be an uncomfortable factor for pedestrians.

  • Understanding wind effects
    Corner effect
    Also known as corner streams or corner jets. The wind speeds up near the corners of buildings. Pedestrian discomfort is mainly due to transition and turbulence.
    Passage effect
    Passage effect can be seen in any passage through a building or small gap between two buildings. Pedestrian discomfort is mainly due to high winds.
    Venturi effect
    Speed up between two buildings or rows of buildings. Pedestrian discomfort is mainly due to high winds.
    Wash down effect
    When hitting a wall, the wind can be redirected downwards and create undesirable effects on pedestrian level. This "vortex" can be observed in front of the high rise building. Behind the building (cavity), small "eddies" can be seen, where the air is mixed by the swirling motion of the wind. Outside of the cavity zone, the air flows in the wind direction
Average
This section shows the wind flow (velocity). Each image is based on the average wind speed, and is visualized in slices. For the side view, the camera is placed orthogonally (90°) to the wind direction and is focused on the building of interest.

  • How to interpret the color scale
    Colors
    Blue colors indicate that the wind speed is reduced, and red colors indicate that the wind speed is increased. The resulting wind speeds are compared to the input wind speed given in the set up.

    The flow is illustrated using two main colors, that are mapped to negative and positive values. Two main colors is typically used when a single channel of data is available (for example velocity, pressure or temperature). The color mapping is linear and relative to this specific simulation.
AverageArrows
This section shows the wind flow (velocity). Each image is based on the average wind speed, and is visualized in slices. Each visualization is also overlapped with arrows, that indicate the wind direction and its dynamics. For the side view, the camera is placed orthogonally (90°) to the wind direction and is focused on the building of interest.

    Finite Element Method
    The foundation of Ingrid Cloud is our CFD-framework, which uses the Finite Element Method (FEM) together with adaptive mesh refinement based on adjoint techniques and a posteriori error estimation. Since 2010, our technology has been regularly validated in benchmark workshops organized by the American Institute of Aeronautics and Astronautics (AIAA) and by NASA. The team behind Adaptive Simulations has dedicated over 30 person-years of research, to solve and automate many typical problems regarding CFD.

AverageStreamlines
The images in this section shows velocity streamlines in different slices from the side. Streamlines indicate directions, followed by a wind particle of the flow. For the side view, the camera is placed orthogonally (90°) to the wind direction and is focused on the building of interest.

Computational mesh
The images in this section show the tetrahedral mesh in cross sections perpendicular to the axis. Each vertex in the mesh can be thought of as a sampling point, where the flow is evaluated. Our adaptive mesh refinement method is capable of identifying regions of the flow requiring higher resolution, depending on the quantity of interest specified in the creation of the simulation, and the residual (the sum of all local errors). Tetrahedra in these regions are subdivided into smaller tetrahedra, increasing the resolution and decreasing the local error. This subdivision continues until the error is sufficiently small throughout the entire domain. This figure shows the sequence of adaptive mesh refinements from the side.

Download RAW dataBuilding
Download building data (CSV) for the simulation. This can be used to find forces and torque. This is a comma-separated values file containing surface load as a function of height. If you have specified a building of interest, the loads are computed for that building; otherwise, loads are computed for the entire model.
