Hy. Yu, A local space-time adaptive scheme in solving two-dimensional parabolic problems based on domain decomposition methods, SIAM J SC C, 23(1), 2001, pp. 304-322
We describe a local space-time adaptive refinement and derefinement method
for solving systems of parabolic partial differential equations. Solutions
are calculated on local spacetime meshes using a domain decomposition finit
e element algorithm in space and an extrapolation algorithm in time. An a p
osteriori spatial error estimate controls a local spatial refinement strate
gy and an a posteriori temporal error estimate monitors temporal refinement
and order of the integration. A multiplicative Schwarz algorithm is used t
o coordinate solutions between overlapping grids. We use nearly minimal ne
meshes which follow the dynamics of the problems in an efficient manner.
