Measuring lattice constant

[hsuya]

After I have optimized a geometry, how can I check what is the lattice constant after optimization?

[Jess Wellendorff]

It will be printed in the log file. But most easy to select the optimizwed BulkConfiguration on the Lab Floor, and use Text Representation widget to see info on lattice constants, atomic positions, etc.

In addition, I would suggest going through our Introduction to QuantumATK to get an overview on basic features of QuantumATK, see https://docs.quantumatk.com/tutorials/intro_quantumatk/intro_quantumatk.html. For geometry optimization, see also https://docs.quantumatk.com/tutorials/geometry_optimization/geometry_optimization.html.
