A nonnegativity preserving scheme for the relaxed cahn-hilliard equation with single-well potential and degenerate mobility

HIGHLIGHTS

• who: Bubba Federica and Poulain Alexandre from the (UNIVERSITY) have published the research: A nonnegativity preserving scheme for the relaxed Cahn-Hilliard equation with single-well potential and degenerate mobility, in the Journal: (JOURNAL) of June/30,/2021
• what: The authors propose and analyze a finite element approximation of the relaxed Cahn-Hilliard equation [Perthame and Eur. The authors propose two different time discretizations leading to a non-linear and a linear scheme. The authors show the well-posedness and convergence of solutions of the non-linear numerical scheme. To circumvent this difficulty a relaxed . . .
