Abstract
The paper presents a workflow for finite element model generation from point clouds acquired via photogrammetry and laser scanning. The case study is a room with an umbrella vault in Castel Masegra, located in Sondrio (Italy). The complexity of the room required an accurate geometric survey from a set of dense point clouds, from which a detailed BIM as well as 2D drawings were generated. Finally, a tetrahedral mesh was derived from the geometric model and was used to run a finite element analysis. The aim of this work is to describe the procedure developed and illustrate the main challenges found.

The paper presents a workflow for finite element model generation from point clouds acquired via photogrammetry and laser scanning
This paper investigates the possibility to transform an accurate and dense point clouds into a 3D finite element model that preserves the geometric irregularities captured by laser scanning or photogrammetry
The case study chosen for this purpose is Castel Masegra, the castle that dominates the city of Sondrio, originally built in the XI century and modified several times
