Wind Loads on an Isolated Building - Validation


#1

Dear SimScalers,

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

\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

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