[Pw_forum] Force and total energy

[zafar rasheed]

Dear All
I calculate the lattice constant of
ZnO. The total energy is minimum at this lattice constant but force
is not zero (P=-20 Kbar) at this lattice consatnt... My question is
that How I can get minimum total energy and zero forces (P=0) at same
lattice constanant....
