Elastic-smoother test does not finish. What do I do wrong?

Hej,

I tried to run the elastic-smoother test in unicorn-hpc/test/elastic-smoother. I followed the instructions in the README file.
It seems like that the program stuck after TimeDependentPDE::step
Here the end of my log file:
...
Mesh quality rank 0:
mu_min: 0.239
mu_max: 0.999
mu_avg: 0.864
mu2_min: 1
mu2_max: 4.19
mu2_avg: 1.17
h_min: 0.205
h_max: 0.614
h_avg: 0.345
bbox_min: [ Point x = -7.27 y = 0 z = 0 ]
bbox_max: [ Point x = -0.759 y = 4.09 z = 3.83 ]
TimeDependentPDE::step

I runned:
mpirun -np 6 ./elastic_test

I'm using the latest unicorn-hpc:
Unicorn 0.1.2-hpc

What do I do wrong?

Best,
Kaspar
