[Pw_forum] vc-relax analysis doubt

[Prasenjit Ghosh]

Dear Ricardo,

Probably your scf is not converging in 100 cycles.....that's why it is
stopping.

Also, as an alternative, you can achieve the same by manually varying your
celldm(3), keeping the in plane lattice vectors fixed.

With regards,

Prasenjit
