Title: error when view electrostatic_difference_potential of graphene junction.
Post by: hung on October 7, 2010, 11:38: hello!
I run a exemple about electrostatic difference potential of graphene junction by VNL. The process is ok, when I view the contour I saw all scale bar is red, it is not true and affter save image it is white, too bad. please help me repair it!

Post by: hung on November 12, 2010, 19:22: my problem is solved. it is not error of VNL, wich is error of PCs hardware. graphiccard is not enough to display. because, when I use a better PC, it ok.

Installing the proper vendor driver for your graphics card seems to solve the issue. We will, nevertheless, make efforts to fix it for ATK 13.8.
