This course provides an up-to-date overview of numerical modelling, which is essential for geotechnical engineering projects. It covers the theoretical and practical principles of the finite element method, demonstrating it to be an indispensable tool for analysing and predict behaviour soils and rocks. The course focuses on Plaxis 2D, industry-leading software, covering everything from the construction of geometry, from mesh generation through to the interpretation of water flow and results. This is complemented by practical case studies, reinforcing the ability analytical skills in the face of real-world challenges. This course refines conceptual understanding and technical application skills, which are vital for professionals keeping pace with innovations and demands in the geotechnical field.
