Problem viewing electron difference potential of graphene junction device

[simba]

I have followed all the steps given in the tutorial of graphene junction device using ATKSE, when i see the contour of electron difference potential this is what i get.

Tell me if and where i am going wrong.

This is a known issue, which occurs when using Mesa (default, generic) video drivers. You can solve it by installing vendor-specific video drivers (Nvidia, ATI, or whichever card you are using).

The problem has been fixed for the next release, so that VNL will support also Mesa.
