A fitted space-time finite element method for an advection-diffusion problem with moving interfaces
Quang Huy Nguyen, Van Chien Le, Phuong Cuc Hoang +1
This paper presents a space-time interface-fitted finite element method for solving a parabolic advection-diffusion problem with a nonstationary interface. The jumping diffusion co…
