GGU-ELASTIC: Step 6: Evaluate

First, the results are to be compared to exact solutions. Using the relationships from the "Grundbautaschenbuch (Volume 1; "Stress determination")" the exact values for this case can be analysed.

Table 1 Settlements [cm] for worked example

x [m]	Results GGU-ELASTIC	exact	Difference [cm]	Difference [%]
0.0000	12.6	12.2	0.4	3.3
0.1875	12.5	12.2	0.3	2.5
0.3750	12.4	12.1	0.3	2.5
0.5625	12.2	11.9	0.3	2.5
0.7500	11.9	11.6	0.3	2.6
0.9375	11.4	11.2	0.1	0.9
1.1250	10.8	10.7	0.1	0.1
1.3125	9.8	10.0	-0.2	-2.0
1.5000	8.8	8.8	0.0	0

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).
