Error estimates for the patch bubble method for convection-dominated channel flow problem
Eberhard Bänsch, Pedro Morin, Itatà Zocola
We present error estimates for the BMZ (Bubble Mesh Zoom) residual-free bubble method applied to a convection-diffusion equation in the convection-dominated regime. The method inco…

Patch bubbles for advection-dominated steady and unsteady problems
Eberhard Bänsch, Pedro Morin, Itatà Zocola
A novel variant of the \emph{residual-free bubble} method (RFB) for advection dominated problems is presented. Since the usual RFB still suffers from oscillations and strong under/…
