LDA+U is one of orbital dependent methods. So to run a LDA+U calculation,
firstly you must create input files for the orbital dependence potentials.
The templates for these files are *case.indm* and *case.inorb* within the *
SRC_templates* directory of the wien2k package. Once you have these files
in your current directory (modify them as you want), use the command
-orb*" to launch yỏu LDA+U calculation. Note, you must run spin-polarized
calculation in order to use orbital potential.

More detail instructions and explanations can be found in the "userguide"
handbook for wien2k which can be downloaded from
