We solve it with the recently introduced radial basis function-based partition of unity method (RBF-PUM), which is a spectrally convergent collocation meshless scheme well suited to this kind of problem. The resulting discrete system of nonlinear equations is tackled with a trust-region algorithm, whose performance is much enhanced by the analytic Jacobian which is provided alongside. Preliminary results up to Re = 60 with just 1292 nodes are shown.6eng© Springer International Publishing AG 2017Numerical analysisComputational fluid dynamicsSpectral methodsconference paperIngeniería IndustrialMatemáticashttps://doi.org/10.1007/978-3-319-65870-4_35open access495507Spectral and High Order Methods for Partial Differential Equations (ICOSAHOM 2016): selected papers from the ICOSAHOM conference, June 27-July 1, 2016, Rio de Janeiro, Brazil119CO/0000010857
