Cylindrical Triaxial Test

Hi All,
I am interested to compare my experimental and FEM results with DEM. I have installed Woo and tring to run Cylindrical tests. However, every time I got error message like as belows.It is noted that I have last used DEM in YADE platform and PFC3D in 2007-2009. I am afraid that I forgot many issues. Any co-operation to resolve the problem will be highly appreciable.
