A non-invasive implementation of a mixed domain decomposition method for frictional contact problems

P Oumaziz, P Gosselet, PA Boucard… - Computational …, 2017 - Springer
A non-invasive implementation of the Latin domain decomposition method for frictional contact
problems is described. The formulation implies to deal with mixed (Robin) conditions on …

Global-Local non intrusive analysis with robin parameters: application to plastic hardening behavior and crack propagation in 2D and 3D structures

I Fuenzalida-Henriquez, P Oumaziz… - Computational …, 2022 - Springer
The global/local analysis allows to embed a specific local zone of interest with a different
behaviour in a global coarse model. In this local model, fine meshes are usually used to model …

A parallel non-invasive mixed domain decomposition-Implementation and applications to mechanical assemblies

P Oumaziz, P Gosselet, PA Boucard… - Finite Elements in Analysis …, 2019 - Elsevier
This paper proposes to confront a mixed domain decomposition method with industrial
computations, in particular the simulation of quasi-static assemblies with frictional contact …

Analysis, improvement and limits of the multiscale Latin method

P Oumaziz, P Gosselet, K Saavedra… - Computer Methods in …, 2021 - Elsevier
