</div>When I use it (with the same settings lda_plus_u and lda_plus_u_kind) for a bulk TiO2 rutile structure, the calculation is running perfectly without any problem !!!  So it seems that indeed, there is problem with the 4.3.2 version and the LDA+U... try to work with <span lang="en"><span>later version</span></span><br>
