Abstract
This paper describes how distributed computing can be
applied in structural design optimization systems in order
to increase the computational efficiency. It is described
where distributed computing can be applied in the design
optimization process and the emphasis is put on the
design sensitivity analysis as this subproblem of the optimization
process is the most obvious choice for distributed
computing. General and efficient expressions for finite element
based design sensitivity analysis of elastostatic and
elastodynamic problems are derived using the direct differentiation
approach, and it is then illustrated how the
public domain code PVM (Parallel Virtual Machine)
can be applied to obtain effective distributed design sensitivity
analysis on a network of heterogeneous UNIX computers.
