We have the following result: 4.1 Slow Manifold Equation
WebThis paper is concerned with the numerical approximation of mean curvature flow t → Ω (t) satisfying an additional inclusion-exclusion constraint Ω 1 ⊂ Ω (t) ⊂ Ω 2. Classical phase field model to approximate these evolving interfaces consists in solving the Allen-Cahn equation with Dirichlet boundary conditions.
