[Pw_forum] usage of recover=.true.

[Changru Ma]

No. What I suggested is exactly what you want. In the first calculation, set recover to false, the code will compute the first 105 modes for you. When it is working on the 106th mode, it stops as you said. Then you modify the input file, turn "recover" to true, run the calculation again and the code is able to recover what you have done and start from the 106th mode. I would suggest you to write to another output. In the output, you will see:

…

Representation    1      1 modes -  Done

…

Representation    105      1 modes -  Done

Representation    106      1 modes - To be done

…

> Thanks a lot for the answer. The problem is I started calculating the phonons at the Gamma point. In my system there are 180 modes and something went wrong with the server so it stopped at the 106.I am doing the 180 in one go! Is there a way to save the 106 ones already done! or u suggest that I calculate each one of them in a separate fie and use recover=.true.?

I have used in my input file recover=.true.  I have reached representation 106 before the server broke down. Does it mean that If I executed the command ph.x again, the calculations will start from where it was interrupted?if not, what can i do to not lose what has been done?
