Hi, First there is a tab after nband, and abinit doesn't like that. Then I'm guessing the computation is to heavy to be performed on only one core, and that is why nothing happens. Indeed, you are talking about parallel calculation, and since you don't have any k-points I guess you are talking band / fft parallelisation. In that case you must put paral_kgb 1 to activate band parallelisation (since abinit 5.6 I'd say, but I'm not sure). You must then specify npband, npfft, npkpt (see http://www.abinit.org/documentation/helpfiles/for-v5.8/input_variables/varpar.html#paral_kgb) Two pther things : - I guess you are computing a molecule, and I guess you want to compute only the gamma point, so you should had shiftk 0 0 0 because default is 0.5 0.5 0.5 - if you want to perform the computation for the isolated molecule, i'd say your box is to small, and you don't need optcell, but that may not be your aim.

However, there is no any SCF step printed out and the calculation seems to run (several wfoptalg values were tried such as 1, 11). Any ideas ? Thank you in advance for the kind help.
