[gmx-developers] A question about dielectric constant

Dear Everyone:
      I have done many simulations. But I found when I add direct electric field along x(y or z) axis for a 100ps~2ns simulation with strength 0.0003V/nm~3V/nm, the dielectric constant  become bigger than 0V/nm. I have set the epsilon-r =0.   I want to know why? I beg your pardon? Even I use the example in http://www.baidu.com/link?url=AqAoJrMvTNF8TEDLInoLj2ySsz4cr0g4ee6kHbHD6H5EwQnlSAJXyHvcdZHUBvTa_KhaXl6nuQEKVVEja-dD99JFUa7XMSqQLiLh88fsnuIS8SvtYmZhakix3bGqgzRm&ie=utf-8&f=8&tn=baidu&wd=gromacs%20tutial&inputT=2426.
 Best wishes,your sincerely
