Abstract :
An upgrade of an a posteriori error-estimation algorithm, based on the residual evaluation, is presented. This extension overcomes a drawback of the original algorithm, which estimates the error just on the solution of the problem, by also estimating the error on the gradient of the solution. For some test cases, the performance of the method is assessed by comparison with analytical results
