[Wien] Reg:LDA+U
If you want a non-magnetic solution with LDA+U you still need a spin-polarized setup, but then can use runsp_c_lapw -orb to constrain the spin to zero.

[Wien] Reg:LDA+U
No, you can not use run_lapw before LDA+U. runsp_lapw needs case.clmup/dn, which are not generated by run_lapw. In general, it's not a good idea to do spin-polarized and non-spin-polarized calculations in the same directory. Also, LDA+U is implemented only with runsp_lapw. F.
