In this paper an Approximate Waves-Bordering algorithm (AWB) is presented. It computes the Finite Elements linear system solution-update after a refinement/un-refinement step. This is done taking into consideration only the equations that corresponds to the nodes whose solution is modified above a certain tolerance and it shows to be very efficient. The algorithm considers an increasing set of equations that updates recursively and stops when the norm of the residual has gone under a user-defined threshold.

Abstract
In this paper an Approximate Waves-Bordering algorithm (AWB) is presented. It computes the Finite Elements linear system solution-update after a refinement/un-refinement step. This is done taking into consideration only the equations that corresponds to the nodes whose solution is modified above a certain tolerance and it shows to be very efficient. The algorithm considers an increasing set of equations that updates recursively and stops when the norm of the residual has gone under a user-defined threshold.File in questo prodotto:
