Witryna9 maj 2024 · For example, extended finite element methods (X-FEM), immersed interface methods (IIM), and multi-scale methods have been developed to solve interface problems of elliptic partial differential equations with an interface-independent mesh, and readers are referred to [5, 9, 19, 32, 39, 40] for more details about Witryna17 sie 2024 · The immersed analysis concept was originally proposed in the context of the finite difference method by Peskin [] in 1972. This immersed boundary method (IBM) and its enhancements have been employed in a wide range of applications ever since (see, e.g., Ref. [] for a contemporary review). The application of the immersed …
