An iterative grid redistribution
method for
singular problems in multiple
dimensions
We introduce an iterative grid redistribution method
based on the variational approach. The iterative
procedure enables us to gain more control of
the grid distribution near the regions of large solution
variations. The method is particularly effective for solving
PDE's with singular solutions (e.g. blow up solutions).
Examples of various applications in two and three dimensions
will be given.
