An adapted deflated conjugate gradient solver for robust extended/generalised finite element solutions of large scale, 3D crack propagation problems
Konstantinos Agathos, Tim Dodwell, Eleni Chatzi +1
An adapted deflation preconditioner is employed to accelerate the solution of linear systems resulting from the discretization of fracture mechanics problems with well-conditioned…
Moment fitted cut spectral elements for explicit analysis of guided wave propagation
Sergio Nicoli, Konstantinos Agathos, Eleni Chatzi
In this work, a method for the simulation of guided wave propagation in solids defined by implicit surfaces is presented. The method employs structured grids of spectral elements i…
Taylor-series expansion based numerical methods: a primer, performance benchmarking and new approaches for problems with non-smooth solutions
Thibault Jacquemin, Satyendra Tomar, Konstantinos Agathos +2
We provide a primer to numerical methods based on Taylor series expansions such as generalized finite difference methods and collocation methods. We provide a detailed benchmarking…
A local basis approximation approach for nonlinear parametric model order reduction
Konstantinos Vlachas, Konstantinos Tatsis, Konstantinos Agathos +2
The efficient condition assessment of engineered systems requires the coupling of high fidelity models with data extracted from the state of the system `as-is'. In enabling this ta…
