Convergence issues are a frequent and complex challenge in geotechnical modelling, often resulting in delays and reduced confidence in simulation outcomes. This session will present a structured approach to identifying and resolving convergence problems within PLAXIS 2D and 3D environments. Participants will gain a clear understanding of solver feedback, learn how to refine model configurations, and explore the role of convergence control parameters in enhancing numerical stability and simulation reliability. The session will also include practical demonstrations to illustrate key concepts and recommended troubleshooting techniques.

Learning Points:

  • Explore the role of convergence control parameters, including how they influence numerical stability and calculation success.
  • Introduce common convergence issues encountered in PLAXIS 2D and 3D simulations and explain their underlying causes.
  • Demonstrate practical troubleshooting techniques using real-world examples to refine model configurations and improve solver performance.
