Constrained minimization problems and FFT-based solvers: application to local Dirichlet boundary conditions and contact mechanics
Lionel Gélébart, Yaovi Armand Amouzou-Adou
The present paper focuses on a recent and active research axis to overcome the limitations of FFT-based solvers in order to apply various types of boundary conditions (BCs) and not…

A robust and versatile parallel FFT-based mechanical solver for general non-periodic and periodic boundary conditions
Yaovi Armand Amouzou-adoun, Lionel Gélébart, Cédric Flageul +1
General boundary conditions are implemented within a fast Fourier transform framework for linear and non-linear mechanical problems using small or finite transformation formulation…
