Re: [Wien] Steps to perform volume optimization of orthorhombic structure

2021-09-30 Thread Peter Blaha

Since version 21 there is a new tool available:

optimize_abc_lapw(for its usage see uG or -h switch)

This is the recommended way to optimize an orthorhombic structure.

PS: Otherwise, since the volume optimization is the most important 
thing, I'd do first a volume optimization and eventually at the optimal 
volume the others.  However, if there are larger changes, you may need 
to do this at least twice (or more), because the optimal b/a depends of 
course also on the optimal c/a,

Dear Wien2k Users,

I am performing volume optimization of orthorhombic structure. There are 
three steps to perform optimization: 1. b/a optimization 2. c/a 
optimization 3. volume optimization.
I performed b/a optimization keeping c/a and volume constant. Now what 
is the next steps for c/a optimization and volume optimization.


Thanks,
Ajay
