Abstract:

The DST Group shape optimisation methodology is well established with several successful implementations to ADF aircraft involving repairs to crack-prone locations. The process involves adaptive reshaping of locally-concave boundaries so as to minimise a stress concentration by spreading the stress more evenly over a longer region of the boundary. DST Group in-house software is used in conjunction with a commercial finite element solver in an iterative manner to achieve this outcome. The prior DST Group software had been found to be dependent on the version of the commercial graphical user interface being used and the software was not readily adaptable to newer versions. The work reported here involves replacing some of the prior code so that the graphical user interface is not used in the process. This document includes a number of 2D and 3D example problems that were used to demonstrate the successful operation of the converted code. The main benefit of the new code is that the software can be ported to other computer hardware without any interaction with the installed graphical user interface, but it also enables a reduction in the use of commercial licenses and provides faster run times.
