Matlab Programs for 1D Adaptive Moving Mesh Methods

This page contains the matlab programs for moving mesh finite difference and finite element methods for the numerical solution of systems of 1D second-order parabolic equations. They can also be used for fixed meshes. Programs for adaptive mesh generation and several example drivers are also provided.

See Chapters 1 and 2 of Huang and Russell: Adaptive Moving Mesh Methods (Springer, New York, 2011) for the detailed description of the methods and examples.
