Naming convention for the pseudopotential

Naming convention for UPF PP files: atomic_symbol.description.UPF

description = [field1-][field2-]field3-[field4-]field5[_field6]

([...]=optional, fields are separated by a dash except the last one)

Table of description fields and of their meaning:

field 1 (optional)

  • rel: full-relativistic

field 2 (optional)
