Error while running 2 tutorials (packedbedtemp & twospheresglowinski)

Hi !!

I successfully ran two tutorial cases (erguntestMPI and settlingtestmpi); the coupling works flawlessly!! However, I encountered the following errors when I ran the packedbedtemp and twospheresglowinski tutorial:

For the cfdemsolverpisoscalar - packedbedtemp:

I tried to fix the errors but I still can't get it to work.. for example for the packedbedtutorial, I tried (according to http://www.cfdem.com/forums/installation-cfdem-0) with two different paths for the probes: both postProcessing/probes/0/p and /probes/0/p ..but the error still persists..

Also, the actual computation for erguntestmpi was successful, for post-proc, I used foamToVTK to get the CFD vtk files but the pizza command (cd DEM) failed to generate any VTK files! instead the following error pops up:

......./DEM$ pizza
Pizza.py (1 Oct 2006), a toolkit written in Python

I use Ubuntu 12.04.5 LTS, OpenFOAM 2.1.1 and the latest LIGGGHTS and CFDEMcoupling package from the github rep..running the cfdemSysTest gives ALL valid for both critical and non critical items.

Any help would be greatly appreciated. Many Thanks in advance!!!
