Abstract: Explicit finite element analysis of contact-impact problems
on parallel computers with distributed memory is concerned. Subject to
the characteristics of finite element method and the structure of
supercomputer, a parallel algorithm is designed for explicit finite
element method based on message passing and domain decomposition. A new
domain decomposition method based on the element type and material model
is specially presented for parallelization of explicit finite element
simulation of crashworthiness. The algorithms have been implemented in
the GEFEP-P software, a self-developed program for simulation of
crashworthiness, on the Shengwei supercomputer. Numerical example shows
that parallel computation improve the efficiency of simulation rapidly.
Key words: Finite element method Parallel computation
