Advances in Numerical Methods for Complex Systems

The field of numerical methods for complex systems is rapidly evolving, with a focus on developing efficient and accurate algorithms for solving nonlinear equations and simulating complex phenomena. Recent developments have centered around the creation of novel finite element methods, such as the weighted implicit-explicit discontinuous Galerkin method and the cut finite element exterior calculus, which offer improved stability and accuracy for a wide range of applications. Additionally, researchers have made significant progress in the development of adaptive time-stepping strategies, such as the Energy-Variation Moving Average technique, which enable more efficient and robust simulations of complex systems. Noteworthy papers in this area include the development of novel superconvergence and ultraconvergence structures for the finite volume element method, which achieve higher-order accuracy and improved stability. Another significant contribution is the construction of basis functions for the geometry conforming immersed finite element method, which enables the simulation of complex interface problems with high accuracy. Overall, these advances have the potential to significantly impact a wide range of fields, from materials science to fluid dynamics.
