Description CFD and FEA analysis of the fence panel type vertical. In this analysis modified model of vertical fence rev. E (fence height reduced by 500mm) panel was checked for strength and displacement under load of the force applied to the panel from wind velocity of 135 km/h. Analysis of the structural stability of the fence model was run from both sides due to different shape of checked panel.

Assumptions Model simulation was carried in two steps:

1. CFD analysis under wind speed of 135 km/h in two directions perpendicular (90deg) to fence surface.

2. FEA of all metal parts in model under load transferred form CFD analysis.
