Running
python solid-conv.py
creates a data file for each element type with the mesh density parameter setting, the number of nodes and the maximum displacement and stress values. An example (C3D8I.txt):
# size NoN smax umax
200 8 0.046205 0.000108
100 12 0.077162 0.000151
50 30 0.089084 0.000164
20 264 0.093441 0.00017
10 1386 0.094022 0.000171
Then, running
python solid-plot.py
generates the following plot of the results normalized by the analytical reference values.
