how to display "cylinder.h5", the result of material_nonlinearity.py

Hi,

Could you please tell me how to display "cylinder.h5", the result of material_nonlinearity.py? Usually, the result file is vtk. But the result of material_nonlinearity.py seems only h5. The OS I use is Lubuntu15.04-64bit on VM Ware player.

Best regards, Takuo Fujita
