Dear Jose,
For the generation of structure file, Can I generate a case. struct
file without using the graphical interface. In wien2k userguide, it ask us
to use w2web to generate the structure file. I want to generate a structure
file without using w2web (graphical interface).
In the meantime, as you mentioned in your last mail, I have checked the
RmtKmax ranging between 3 to 8. But then also I observe the error as:
Error in LAPW1
'INILPW' - can't open unit:
18
'INILPW' - filename:
bise.vsp
'INILPW' - status: old form:
formatted
'LAPW1' - INILPW aborted unsuccessfully.
Hope someone might have resolved this. If still there is any possibility,
please kindly inform. Thanks for your kind suggestion.
Regards
M. P. Ghimire
