Research project
Variable fidelity multimodel multidomain coupling approach
FSI based on a partitioned approach, coupling solvers with
different levels of fidelity to speed-up full order aeroelastic analysis.
Coupling in time ⇒ hierarchical approach
Coupling in space ⇒ hybrid approach
Switch during the simulation between full/low order model and
multigrid to accelerate the convergence of high fidelity subiterations.
Adaptive ROM by basis enrichment
During the RANS simulation ⇒ extract low-order subspace
ROM used to continue the simulation while the solution error
is sufficiently small.
If error rises ⇒ return to a full order model initialised by ROM
RANS simulation will continue and will update the subspace
until the ROM can be used again.
