[Wien] Energy vs Volume is linear!

[Marzieh Gh]

Dear Prof.Blaha & Tran

I have calculated optimization of supercell (1*1*2). But Energy vs Volume
is linear!

case.outputeos:

   10575.3364   -88567.151612
   11162.8553   -88566.366642
   12925.4112   -88561.471064
   11750.3745   -88565.095045
   12337.8929   -88563.437182

Is this normal?  If no what is reason? What do I do?

Please help me

Best Regards
