文摘The present contributions deal with the development and implementation of the direct and adjoint incompressible Navie-Stokes equations in a matrix-free time-stepping context making use of the open-source OpenFOAM~ （open source field operation and manipulation） C ＋ ＋ tool- box. It is shown that a few minor modifications in the source code can enable these multi-purpose computational fluid dynamics （CFD） solvers to carry out global instability analysis of three- dimensional flows of engineering interest, exploiting all additional capabilities of such codes. The strength of this methodology is demonstrated through the analysis of an interesting selection of ooen and wall-bounded flows.
