[Wien] Avoid leak out of MT sphere with lower RMT values???

2014-02-15 Thread Kondaiah Samudrala
Dear Tran and Stefan

I have the same problem(core leakage with MT sphere) till now. I tried with
-10 Ry core-valance energy.

Pls explain me dentally about this part



If
you have core leakage, inspect in case.outputst whether you can take
some high-lying core states as valence states instead (these are the
ones that are responsible for the leakage, and if they become valence
states their leakage does not matter any longer).

with regards

S. Appalkondaiah

There is a detailed example at the wien2k website, sec. 7.1.2 of this 
document:

There is a lecture note on Piezoelectricity and another on BerryPI on 
the Wien2k website
