Abstract An important step in any finite element analysis is to determine the accuracy of the model used. For linear elastic analyses, accuracy can be measured by the convergence of the solution. Typically error norms based on the strain energy of the system are employed. However, this method of error calculation is ineffective in regions of large stress gradients or concentrated loads. This paper studies the effectiveness of including an a posteriori L 2 error norm to measure the convergence… CONTINUE READING
