The term "automatic refinement" refers to software-driven processes in which raw data, inputs, or models are algorithmically enhanced, corrected, or optimized without manual intervention. The goal is to increase the accuracy, relevance, or quality of the results. This concept is applied in various domains such as data processing, AI, search engines, or graphical modeling.
In numerical simulations - especially within Finite Element Method (FEM) or Computational Fluid Dynamics (CFD) - "automatic refinement" refers to the self-adjusting process of refining the computational mesh or model in certain regions to enhance simulation accuracy. This typically occurs in areas with complex geometries or where steep gradients in the results are observed, such as stress concentrations, flow separation zones, or material interfaces.
