Dear all:

I met a problem in the calculation of single europium doped diamond. lapw1 will crash In the first scf iteration. The 'uplapw1.error' file shows as follows:

Error in LAPW1
 'SELECT' - no energy limits found for L= 0
 'SELECT' - E-bottom   -5.02500   E-top -200.00000

Part of struct file is pasted as follows:

.................................

Because this file is so long that I can't place all in this mail. If necessary, I can put the rest part in the later email.

I made a lot of attempts according to the past mail in the maillist, like change the Rmt in struct file, and change the linearization energy for Eu's s state. It still doesn't make any difference. I wonder anyone can give me some suggestion. Thank you in advance.
