Abstract
A Petrov4alerkin formulation based on two different perturbations to the weighting functions is presented.
These perturbations stabilize the oscillations that are normally exhibited by the numerical solution of the
transient advective-diffusive equation in the vicinity of sharp gradients produced by transient loads and
boundary layers. The formulation may be written as a generalization of the Galerkin Least-Square method.
