<div>Hi Nek's,<br clear="all"></div><div><br></div><div>I would like to start using the perturbation mode for a fully three-dimensional case, however I have no idea about how it works.<br></div><div>What I have understood so far is that I've got to change the lp-parameters in my SIZE file. Apart from these changes, what else do I have to do? Do I specify my input file containing my base flow as in a classical restart procedure or elsewhere?</div>
