A topology optimization algorithm for electroelasticity coupled problems
St. Petersburg Polytechnical University Journal: Physics and MathematicsA problem of applying topology optimization to elastic deformable bodies exposed to coupled electric and mechanical fields has been studied. The main goal was to find the optimal distribution of electric and mechanical properties in the given area ...

Block Preconditioners for Coupled Physics Problems [PDF]
SIAM Journal on Scientific Computing, 2013 Finite element discretizations of multiphysics problems frequently give rise to block-structured linear algebra problems that require effective preconditioners. We build two classes of preconditioners in the spirit of well-known block factorizations [M. F. Murphy, G. H. Golub, and A. J. Wathen, SIAM J. Sci. Comput., 21 (2000), pp. 1969--1972; I. C.

Coupled Dynamical Systems for Solving Linear Inverse Problems
MathematicsWe propose a class of coupled dynamical systems for solving linear inverse problems, treating both the unknown variable and an auxiliary variable representing measurement dynamics as state variables. This framework does not rely on probabilistic modeling

Coupled techniques for the simulation of fluid-structure and impact problems
Computer Assisted Methods in Engineering and Science, 2023 The ability to model the different regimes of a physical event using different numerical techniques has a number of advantages. Instead of applying the same general solver to all domains of a problem, a solver optimized for a particular regime of ...
