Dear Tran,

I have tried setting Lmax=8, I still get the same error. I have check 
case.r2v_nlvdw is not empty and L goes up to 8. The reason why I want to expand 
Lmax to 10 is because I require the accurate electron density information for 
further analysis.

Best regards,

主题: Error related to nlvdw calculations

Dear WIEN2k developers and users,
I am trying to do a calculation on some layered materials by including the 
nlvdw correction into SCF calculation in Wien2k 17.1 running at Linux system 
(Intel E5-2680, CentOS 7 Linux 64 bit) with intel compilers. The calculations 
are successful without the calculation of the potential; however, I always get 
errors when I switch on the potential calculations. In the beginning, when I 
set "calculation of the potential (T or F)" to "T" in case.innlvdw, I always 
get the error “Insufficient virtual memory”. According to the suggestion from 
the previous post, in the line 41 in SRC_nlvdw/calc_vvdw.F, add : lmtmp =0 and 
recompile a selected package : nlvdw. The error “Insufficient virtual memory” 
is solved. But then I always get the following errors:
In case.dayfile,    start (Wed Sep 13 00:35:04 CEST 2017) with nlvdw (200/99 to

For the calculations, I set kpoints=605, RKmax=10, and expand lmax to 10 in 
I have tried running in both single mode or parallel mode and I get the same 
error. Does anyone have any suggestion on how to fix the problem. Thanks in
