In this work, we introduce the novel application of the adaptive meshrefinement (AMR) technique in the global stability analysis of incompressibleflows. The design of an accurate mesh for transitional flows is crucial.Indeed, an inadequate resolution might introduce numerical noise that triggerspremature transition. With AMR, we enable the design of three different andindependent meshes for the non-linear base flow, the linear direct and adjointsolutions. Each of those is designed to reduce the truncation and quadratureerrors for its respective solution, which are measured via the spectral errorindicator. We provide details about the workflow and the refining procedure.The numerical framework is validated for the two-dimensional flow past acircular cylinder, computing a portion of the spectrum for the lineariseddirect and adjoint Navier-Stokes operators.
