That example is the only one that cannot run in parallel (i.e. with MPI), because I use a trick inside the code to include a mathematical crack. Thus always run it with nproc = 1. I'll add a note in the README file of that example.

In |Rayleigh_wave_with_crack| example, if you change |nproc = 4|, the outputs are different with |nproc = 1|.
For |np=1|, I get following output: https://youtu.be/ztzRk1ccUpc , For |np=4|, I get following output: http://youtu.be/wv5ekGsURaQ .
I think the results should keep the same for different np. Do I make a mistake here?
