<div>Hi, </div>
<div>if you wanna dig out some useful information related to your question , </div>
<div>you can try to search with google , refined keywords with 'pwscf' or others.</div>
<div> </div>
<div>Please read the instructions such as INPUT files in $espresso/Doc, or tutorials mentioned in Axel and nicola's last mails.</div>
<div> </div>
<div> </div>
<div>hope help.</div>
<div> </div>
<div>regards,</div>

<br><br> because we made the choice to make the code better than the manual, rather the<br>the other way around ;-)<br><br> <br> Respected Users,<br><br> >>>>>>>>>> It's definitely Good Choice
<br> but not the best !!!!! It would be better if the manual and the code - both are <br> equally good.<br> Writing a good manual is not as difficult as writing a beutiful code.<br> I think any project asistant can do it.
<br> I don't know why in Example directory there are so many simple example programs<br> (<br> Al , Ni, Cu, C,<br> Si, etc. etc.)???????? It would be better if there is some simple examples and at<br> least one example of
<br> some complex material of some difficult structure (i.e. non cubic say monoclinic<br> structure).<br> You know there are so many tutorial on how to handle simple cubic system.<br> But no (as far as I know) tutorial on how to construct a supercell for a monoclin
<br> ic structure?????<br> I think my question is not a stupid one. Because I have checked almost all the <br> letters of the PWFORUM<br> and almost half of them are just trivial one (like What's the difference between
<br> alat and bohr??? Is it posiible to include<br> spin in PWSCF???? How to calculate electron phonon coupling using PWSCF????? All<br> are very very trivial<br> questions.). What do you people think???????<br>
If you think that PWFORUM is only for experts then you can creat another forum PW<br> FORUM_for_novice.<br> Because it's very difficult to find out useful informations in the sea of trivial questions.<br> I really want to learn how to handle the complicated structures in pwscf????
<br> More specifically, construct a supercell for non-cubic structures to introduce A type , G type and C type<br> antiferromagnetism in the system.<br> Please don't tell me to ask the Superviser or colleague.<br>
Because most of the colleagues just use all the input files given by their Supervisers blindly.<br> That's why for a new structure again they have to look for their Guide.<br> I prefer to learn the stuffs myself deriving them, reading books , searching nets etc. etc.
<br> I think it would be better if some experts give some useful hints for difficult problems instead of<br> giving 1000 simple examples (spoon feeding!!!!!!!!!!). What do you think??????<br> I'll be highly obliged if you kindly give me some useful references for supercell construction.
<br><br> By the way, many many thanks for all who gave me a long reply and informations about references on the<br> web.<br><br> With best regards,<br><span class="sg"> Amit<br><br><br></span></blockquote></div><br>
