[Pw_forum] Putting a strain on a BCC

[Ben Palmer]

Hi everyone,

I have a BCC and I'd like to put a strain on it, but I want a different
strain in each direction.  Can I specify for example celldm(1)=1.02
celldm(2)=1 celldm(3)=1, or must all three lengths be equal?  Would I need
to use another ibrav?  Sorry if there is a simple answer to this.

Thanks
