Dear SimScalers,

in this weeks spotlight we will have a look at a CFD simulation of **wind loads on a building** by @anon5983385.

## \underline{\textbf{Introduction}}

This project analyses the steady-state flow around an isolated building. The aim is to validate the flow around the building against experiments carried out at the Japan Wind Institute. An atmospheric boundary layer profile is implemented at the inflow.

## \underline{\textbf{Geometry}}

Format: **STL**

#### **Original Model:**

## \underline{\textbf{Mesh}}

Type: **[Hex-Dominant Parametric](https://www.simscale.com/docs/content/preprocessing/meshing/hex_dominant_parametric.html)**

The geometry was meshed using hex-dominant parametric mesh with refinements. The mesh is shown in figure below.

Hello. I want validation my case with AIJ case A but I have some problem in it. for example I don’t know what should I do for setting non uniform initial condition. as I know for non uniform initial condition I should use setfieldDict but I don’t know how.could you please give me some explains.
