hello,
i'm making simple tests with the new pw 1.3.0 version of the code.
I use i.f.c-8.0 with mkl-6.1 on a linux pc.
I have this stop problem, trying to relax with damped dynamics.
forrtl: severe (59): list-directed I/O syntax error, unit 4, file
/tmp//silicon.md
I notice that some silicon coordinates are set to 'infinity' after
few dynamical steps ?!
I attach the input, output and silicon.md files .
thanks.
I
