I have another question on the topic. Does this problem also affect
the other quantities such as electron density, DOS and forces? If I

Thank you for your replies.

Sometimes I have this problem after I use w2web in GNOME or KDE
running via NX (it's a protocol which allows to run remote X session).
After I close the session, the w2web starts to create many processes
and consume 100% CPU.
The solution I use is to killall w2web and restart it again.

Further tests have shown, that changing the mixing method (e.g. MSEC

1. Wien2k is supposed to work on any Linux distribution.

The most simple and painless way of getting rid of this (very common)

Hi,
I've posted the similar question some time ago, please search the list

of this warning by minimizing atomic positions for TiO2 (mini script).
