Title: LDA and GGA

Dear Abiniter,
My calculation with LDA and GGA end up with big difference in Total Energy.
In LDA,Etotal=174 har,while in GGA it's 166 har. Dose that make any sense?
By the way,all the other variables(such as ecut,ngkpt...) are the same in LDA
and GGA calculation.

Best,
Zhang,Waigen
