 Error in the computation of the linearised stresses vs. CPU time needed to solve the problem using FEM
 :::::
 
-The last two bullets lead to an issue that has come many times when discussing the issue of convergence with respect to the mesh size with other colleagues. There apparently exists a common misunderstanding that the number of _elements_ is the main parameter that defines how complex a FEM model is. I have seen a lot of graphs where a certain result is plotted against the number of elements
