<p>Do you have this:</p>
<p>username@computername:~/wiendata/test$ run_lapw -orb -dm<br>
hup: Command not found.<br>
ERROR: option -orb does not exist !<br>
ERROR: option -dm does not exist !<br>
</p>
As was posted recently, a non-spin polarized calculation (run_lapw)
does not have -orb [1].<br>
<br>
For DFT+U, you have to use either "runsp_lapw -orb" or "runsp_c_lapw
-orb" [2]. It says exactly that in the WIEN2k 17.1 usersguide [3]
in section "4.5.6 Orbital potentials" on page 47 were it has:<br>
<br>
<i>Note, you must run spin-polarized in order to use orbital
potentials.</i><br>
<br>
Also, "runsp_c_lapw -h" for example gives:<br>
<br>
-dm -> calculate the density matrix (when -so is set, but
-orb is not)<br>
<br>
So based on the description, -dm could be used if doing DFT+SO:<br>
<br>
runsp_c_lapw -so -dm<br>
<br>
but "runsp_c_lapw -so -orb -dm" and "runsp_c_lapw -orb -dm" should
be incorrect and just "runsp_c_lapw -so -orb" (DFT+SO+U) and
"runsp_c_lapw -orb", respectively.<br>
