Hi Battalgazi,

Since you already can drive your simulation with Python, another
relatively simple way (until ParaView directly supports it) could be
to add to your Python code to update the ParaView scene every time
after you write the simulation data.
http://paraview.org/Wiki/ParaView/Python_Scripting

I may be wrong in details since I have done this only in C++ not in
Python, but the steps should look something like
- mark anyhow your ParaView reader as modified
- reader.UpdatePipelineInformation() to rescan the timesteps
- reader.UpdatePropertyInformation() to pull the updated timesteps
- get the last element of reader.TimestepValues
- set the view.ViewTime to the last timestep
- (optional) rescale the range of the color lookup table
- view.StillRender()
