The results deviate by a maximum of 3.3 % from the exact solution.
If you are interested, as in this case, only in individual values at certain nodes, this can be achieved most simply via the "Evaluation/Individual values" menu item. After selecting this menu item, left-click the required node. The dialog box below shows the result for the first row of Table 1 (foundation centre at x = 0.0 m).
