abstract = {<p style="text-align: justify;">The main purpose of this work is the efficient implementation of a multigrid algorithm for solving Navier-Stokes problems at low Reynolds numbers in different triangular geometries.
In particular, a finite element formulation of the Navier-Stokes equations, using quadratic finite
elements for the velocities and linear finite elements to approximate the pressure, is used to solve
the problem of flow in a triangular cavity, driven by the uniform motion of one of its side walls. An
appropriate multigrid method for this discretization of Navier-Stokes equations is designed, based
on a Vanka type smoother. Moreover, the data structure used allows an efficient stencil-based
implementation of the method, which permits us to perform simulations with a large number of
unknowns with low memory consumption and a relatively low computational cost.</p>},
