Prof Albert Groenwold

Professor: Mechanics Division





​​Prof Albert Groenwold currently is Professor of Mechanical Engineering in the Structural Mechanics Division of the Department of Mechanical and Mechatronics Engineering at the University of Stellenbosch. His fields of interest include structural and multidisciplinary optimization, the development of algorithms for structural and multidisciplinary optimization, and general mathematical modeling.

 

This includes sequential approximate optimization (SAO), general structural optimization (including topology optimization), the development of algorithms for very large scale (VLS) optimization, high performance (green) computing, parallel computing on both the CPU and GPU, and Sparse Algebra representations.

 

He is also interested in metaheuristics, in particular particle swarm optimization (PSO), genetic algorithms (GAs) and differential evolution (DE); not per se only in applying these algorithms to problems of practical interest, but in analyzing the heuristics themselves (in a probabilistic sense), e.g. the lack of invariance of these algorithm, etc.

 

In recent years, he started working on simultaneous analysis and design (SAND). Currently, his interests in SAND are mainly focused on algorithms for local stress constraints (including local stresses in layered orthotropic composite structures). This per se necessitates the development of algorithms that can handle equality constraints in settings where the Hessian matrix is indefinite of negative-definite.

 

Currently, he is studying the development of iterative optimization-based algorithms for singular value decomposition (SVD) and eigenvector extraction. In addition, he also started studying topology-based optimization methodologies for optimal lay-out problems in environmental and sustainability modeling (solar heliostat, and in particular, wind-farm turbine lay-out).

 

An ongoing interest is global optimization of mostly differentiable functions, but also continuous, non-differentiable functions.
