xmdf files generated by pyurdme examples faulty

[somathias]

When opening the xmdf files generated by the simple_diffusion example using paraview 4.4.0, the stored data values of the simulation are really small, ~ 10^-16 to 10^-21, ie. basically zero. Only the initial configuration seems to be stored with correct values.

I also ran the coral_reef and cylinder_demo examples, same problem.

I think the numbers are “correct", but they are in concentration units (molecules/m^m3). If Paraview is not capable of rescaling the output in the visualization, we might have to apply some scaling ourselves.

Verified. The problem is that the data range is too small to render in Paraview. Not sure if this should be treated as a bug in pyurdme or Paraview.
