We are interested in the modelling of saturated thermo-hydro-mechanical (THM) problems
that describe the behaviour of a soil in which a weakly compressible fluid evolves. It is used …

The generalized Golub-Kahan bidiagonalization has been used to solve saddle-point
systems where the leading block is symmetric and positive definite. We extend this iterative …

Nonlinear multi-point constraints are essential in modeling various engineering problems,
for example in the context of (a) linking individual degrees of freedom of multiple nodes to …

We study an inexact inner–outer generalized Golub–Kahan algorithm for the solution of
saddle‐point problems with a two‐times‐two block structure. In each outer iteration, an inner …

Finding a robust and efficient solver for (non-) symmetric systems that arise in
incompressible Computational Fluid Dynamics (CFD) is of great interest to both academia …

Nous nous intéressons à la modélisation de problèmes thermo-hydro-mécaniques (THM)
qui décrivent le comportement d'un sol dans lequel évolue un fluide faiblement …

Deflation techniques are typically used to shift isolated clusters of small eigenvalues in order
to obtain a tighter distribution and a smaller condition number. Such changes induce a …
