Abstract
The application of the non-overlapping domain decomposition
method to finite element problems involves the
partitioning of the complex geometry into an appropriate
number of disjoint subdomains and the solution of
the local and the global problem. In terms of finite element
discretisation the partitioning is based on an element
distribution. Automatic domain partitioning ensures
a balanced distribution according to the expected
computational effort spent in the assembly and solution
steps of the finite element procedure. The load balance
is destroyed in adaptive finite element computations with
a-posteriori error estimation and local mesh refinement
procedures. A dynamic load balancing method was implemented
based on the multistage diffusion method. The
parallelization of the finite element method is described
with emphasise on the adaptive load balancing and an
example is given.
