Dear WIEN users<br>
I am trying to calculate the plasma frequencies, so I calculate<br>
x lapw2 -fermi<br>
x optic<br>
x joint<br>
<br>
I have two comments in relation to the imput (<case>.inop) to the
optic program;<br>
I find that the manual says for the imput (<case>.inop)<br>
<br>
---------------- top of file: case.inop --------------------<br>
99999 1 : NKMAX, NKFIRST<br>
-5.0 2.0 18 : EMIN, EMAX, ***** NBvalMAX *****<br>
2 : number of choices (columns in *symmat)<br>
1 : Re xx<br>
3 : Re zz<br>
OFF : ON/OFF writes MME to unit 4<br>
------------------- bottom of file -------------------------<br>
The Usersguide says in reference to the second line;<br>
nbvalmax <b>optional</b> input. Setting this to the number of
occupied bands <br>
(see case.output2) will reduce cpu-time of
optics <br>
(for large cases, MM only between occupied and
empty bands)<br>
<br>
<br>
I find that this parameter is not optional, that is, if it is not put a
number the program stops! So, if one does not want to put the number
given in <case>.output2, what should one put? 99999?<br>
<br>
<br>
<br>
Lines after 'OFF'<br>
I find that I need to put extra lines after this line, otherwise the
program crashes!<br>
<br>
Yours<br>
<br>
