1.1.13 Analysis of a heterogeneous cube using the iterative linear equation solver

Product: ABAQUS/Standard  

This example demonstrates the use of the iterative linear equation solver in ABAQUS/Standard for a simple static perturbation analysis of a heterogeneous cube. It also demonstrates the effect that material properties have on the convergence of the iterative solver. It should be noted that this problem is much too small for the iterative solver to outperform the direct equation solver and is used only for demonstration purposes.
