Advancements in Numerical Methods for Complex Systems

The field of numerical methods for complex systems is witnessing significant advancements, driven by the need for more accurate and efficient simulations. A key direction is the development of novel finite element methods, such as the enriched Galerkin method and the Zipped Finite Element Method, which offer improved stability and convergence properties. Another area of focus is the creation of adaptive methods, including p-adaptive high-order mesh-free frameworks, which can effectively capture complex geometries and highly non-linear regions. Additionally, researchers are exploring new techniques for solving specific problems, such as the Ginzburg-Landau equation and the Boltzmann-BGK equation, using innovative methods like the fully implicit Crank-Nicolson discontinuous Galerkin method and a modified BGK collision operator. Noteworthy papers include the proposal of a stabilized coupling of conforming and mixed finite element spaces for wave propagation in thermo-poroelasticity, and the development of a provably fully discrete energy-stable and asymptotic-preserving scheme for barotropic Euler equations.
