Dear ABINIT friends,

Since a couple of months I'm using ABINIT to model chemical reactions on metal slabs.

In general ABINIT works well and the calculations succeed.

However in most, if not all, calculations the convergence of total energy is quite slow.

I tend to build up the accuracy of my calculations. At the end of this sequence, the convergence speed becomes a real bottleneck.

So the question arises how can I mitigate the decreased convergence speed.

Any help is welcome!

I have included an input and output file.
