When I try lineral_viscoelastic.py from examples and then see results via postproc.py I see 5 blocks of blue colors which differs from results show in manual. The result is the same no matter how many time steps I set or which time step I currently see in Maya.

When I run it like this:

python examples/linear_elasticity/linear_viscoelastic.py block.h5

I see error because there is no block.h5 yet. So instead firstly I run:

./simple.py examples/linear_elasticity/linear_viscoelastic.py

which creates block.h5 file, and then:

./postporc.py block.h5

I try to understand the logic of simulating viscoelastic behaviour over time through the Sfepy. That seems too complicated to me yet. But even standard example didn't work for me. What may cause the problem?
