Numerical homogenization methods for parabolic monotone problems

چکیده
In this paper we review various numerical homogenization methods for monotone parabolic problems with multiple scales. The spatial discretisation is based on finite element methods and the multiscale strategy relies on the heterogeneous multiscale method. The time discretization is performed by several classes of Runge-Kutta methods (strongly A−stable or explicit stabilized methods). We discuss the construction and the analysis of such methods for a range of problems, from linear parabolic problems to nonlinear monotone parabolic problems in the very general Lp(W 1,p) setting. We also show that under appropriate assumptions, a computationally attractive linearized method can be constructed for nonlinear problems.

Linearized Numerical Homogenization Method for Nonlinear Monotone Parabolic Multiscale Problems
We introduce and analyze an efficient numerical homogenization method for a class of nonlinear parabolic problems of monotone type in highly oscillatory media. The new scheme avoids costly Newton iterations and is linear at both the macroscopic and the microscopic scales. It can be interpreted as a linearized version of a standard nonlinear homogenization method. We prove the stability of the m...

متن کاملFinite element heterogeneous multiscale method for nonlinear monotone parabolic homogenization problems
We propose a multiscale method based on a finite element heterogeneous multiscale method (in space) and the implicit Euler integrator (in time) to solve nonlinear monotone parabolic problems with multiple scales due to spatial heterogeneities varying rapidly at a microscopic scale. The multiscale method approximates the homogenized solution at computational cost independent of the small scale b...
متن کاملNumerical Solutions of Nonlinear Parabolic Problems by Monotone Jacobi and Gauss–seidel Methods
This paper is concerned with solving nonlinear monotone difference schemes of the parabolic type. The monotone Jacobi and monotone Gauss– Seidel methods are constructed. Convergence rates of the methods are compared and estimated. The proposed methods are applied to solving nonlinear singularly perturbed parabolic problems. Uniform convergence of the monotone methods is proved. Numerical experi...
متن کاملCorrectors for the Homogenization of Monotone Parabolic Operators
In the homogenization of monotone parabolic partial differential equations with oscillations in both the space and time variables the gradients converges only weakly in L p. In the present paper we construct a family of correctors, such that, up to a remainder which converges to zero strongly in L p , we obtain strong convergence of the gradients in L p .
