Hybrid explicit–implicit learning for multiscale problems with time dependent source

Y Efendiev, WT Leung, W Li, Z Zhang - Communications in Nonlinear …, 2023 - Elsevier
The splitting method is a powerful method for solving partial differential equations. Various
splitting methods have been designed to separate different physics, nonlinearities, and so …

Constraint energy minimizing generalized multiscale finite element method for multi-continuum Richards equations

T Mai, SW Cheung, JSR Park - Journal of Computational Physics, 2023 - Elsevier
In fluid flow simulation, the multi-continuum model is a useful strategy. When the
heterogeneity and contrast of coefficients are high, the system becomes multiscale, and …

A discontinuous Galerkin method for a coupled Stokes–Biot problem

M Zhou, R Li, Z Chen - Journal of Computational and Applied Mathematics, 2024 - Elsevier
The interaction between fluid and poroelastic structure is a complex problem that couples
the Stokes equations with the Biot system. In this work, we rewrite the poroelastic equations …

format are presented to solve the coupled Brinkman–Darcy flow and transport model. The …

Approximate solution of the Cauchy problem for a first-order integrodifferential equation with solution derivative memory

PN Vabishchevich - Journal of Computational and Applied Mathematics, 2023 - Elsevier
We consider the Cauchy problem for a first-order evolution equation with memory in a finite-
dimensional Hilbert space when the integral term is related to the time derivative of the …

Partially explicit splitting method for a multi-physics problem

WT Leung, W Li - Journal of Computational and Applied Mathematics, 2024 - Elsevier
Multi-physics are widely studied and used in numerical analysis and simulation. Physics-
