Accuracy Of The Solution Scheme

The accuracy of the staggered solution scheme can be improved by increasing the number of iterations and/or by decreasing the time step. Increasing the number of iterations of the staggering scheme is a time consuming process. The accuracy of the proposed methods is based on the selection of the appropriate time step. In all of the following analyses no iterations have been made for the purpose of improving accuracy. The staggered displacement method and the modified staggered pressure method are compared with the finite element solution of example problems for the purpose of evaluating the accuracy of the analysis.
