A modified Allen–Cahn equation with a mesh size-dependent interfacial parameter on a triangular mesh

J Yang, J Wang, S Kwak, S Ham, J Kim - Computer Physics …, 2024 - Elsevier
In this article, we propose a modified Allen–Cahn (AC) equation with a space-dependent
interfacial parameter. When numerically solving the AC equation with a constant interfacial …

Discontinuous Galerkin method for the coupled dual-porosity-Brinkman model

R Li, M Zhou, L Bu, Z Chen - Computers & Mathematics with Applications, 2024 - Elsevier
In this paper we use the weighted discontinuous Galerkin finite element method to solve the
dual-porosity-Brinkman coupling model. The dual-porosity model describes fluid flow in a …
