Surrogate modeling

Composite tape-spring hinge (CTSH) is a simple yet elegant mechanical component for various deployable space structures. This paper formulates and addresses cut-out shape optimization of a CTSH, which is seldom touched upon in literature. Both the maximum strain energy stored during the folding process as well as the maximum bending moment during deployment were maximized in a concurrent way, and the multi-objective optimization problem was realized by merging data-driven surrogate modeling and shape optimization.

In March 2021, The University of Manchester signed a 10 year collaboration agreement with the UKAEA, resulting in a £15M investment for two new research groups; Digital Engineering and Tritium. I lead the Digital Engineering group. The aim is to build a virtual garage where engineers can try out new designs for fusion reactors more quickly than building full-scale prototypes.

A program for 3 way coupling between open-source software Elmer FEM, OpenFOAM and Dakota has been developed.

The program along with examples can be found here: https://github.com/AnjaliSandip/ElmerFEM-OpenFOAM-Dakota

Capabilities: The interface provides an open-source framework that integrates data analytics, finite element and finite volume methods.
