The following image shows the specific static analysis settings required when selecting the soil display type “2D | Stiffness Modulus Method (Elastic Half-Space)” in RFEM 6 may appear. In this dialog box, you can change the number of iterations and the convergence for the iterative determination of foundation parameters. More information on the theoretical basis of this method at [005893#h-4 2D | Stiffness Modulus Method (Elastic Half-space)]].
Maximum Number of Iterations
This text box determines the maximum number of iterations to be performed in order to determine the foundation parameters. An increase may lead to the successful calculation of a non-converging analysis.
Precision of convergence criteria
By changing the value in this text box, you can affect the calculation accuracy. Explicitly related to the stiffness modulus method, how exactly the soil contact stress field between two iterations have to match in order to be evaluated as successful. A lower factor leads to increased accuracy.
