Early Stage Researcher 5 at ENGYS
Intuitive interfaces for optimisation parameterisation, constraint definition and automated mesh-to-CAD conversion
Note: this position has been filled.
While CAD-free optimisation methods are becoming more popular, the interface with the upstream and downstream components of the workflow still lacks sophistication. In this context two elements dominate the tasks of this project:
- return to CAD - conversion of node based data to CAD format using evolutionary algorithms, and
- providing an effective methodology and interactive graphical user environment for defining optimisation constraints on a CAD geometry.
The these two capabilities will allow efficient transition from CAD-free to CAD-based optimisation frameworks and should improve integration of adjoint based optimisation methods into existing product design and PLM systems. Additional workflow elements will focus on providing a more natural user interface for multi-objective optimisation and non-geometric constraint definition.
Objectives:

- M9-M18: Basic implementation of NURBS Symbolic Regression with discontinuity detection and filtering/smoothing of input data. (WP3).
- M18-M24: CAD GUI interface based on VTK/OCCT/HELYX, Secondment to KTW (WP5).
