Finite Element Modeling Considerations of Deep Foundations. The Control Instruments in the Discretization Mesh Generation at the Pilot-Raft Interaction Point

Abstract

The article aims to give a less theoretical and more practical definition to the tool called Subregion, from which the advantage of directly controlling the stiffness of the scraper slab without bringing an additional load of its own weight to the pilot's head can be concretely demonstrated. Deep foundations will therefore be analyzed. The Subregion is extremely useful in finite element modeling because it helps define caps without breaking the continuous surface of tile elements. This aspect will be covered in detail in the article, such modeling with Subregions leads to high-performance computational models, optimal from the point of view of file sizes. From practice, the author will present two case studies, concluding on the optimal ratio between the precision of the calculations and the volume of probable errors at the level of the results.
