Dear Wien2k Users
 
My question is how to calculate total energy of solid? because i want to calculate the total energy difference between antiferromagnetic and ferromagnetic state. 
This total energy is it obtained from optimization of structure (total energy as a function of te cell volume)?
 If this is the case, how can i choose a serial of volumes? are there arbitrary?
Can you please help me to solve this problem ?
 
Thanks a lot.
