<p dir="ltr">If you are trying to converge a calculation with many k-points, there is nothing you can do.</p>
<p dir="ltr">If you are just trying to run lapw1 you can edit the definition file so instead of going to case.vector it goes to /dev/null, for instance. (Don't set SCRATCH as /dev/null, that is a sin.)</p>
<p dir="ltr">x lapw1 -d<br>
edit lapw1.def<br>
lapw1 lapw1.def</p>
<p dir="ltr">Be aware that you won't be able to do much after this, all you will have is the case.scf1 and output files which you will need to edit to find what you want.</p>
<p dir="ltr">Or buy a USB drive.<br>

<div dir="ltr">Is it possible to turn off writing the vector file in the scf run? I'm trying to do a calculation with very fine k-mesh. But the disk space of my computer is limited.
