The problem is probably due to "lnsmax = 4" in the file
$WIENROOT/SRC_nlvdw/modules.F since 2*lnsmax=8 is smaller than 10.
So, set "lnsmax = 5" and recompile the nlvdw package (don't forget
to do "cp nlvdw .." and "cp nlvdw_mpi ..").
Does it solve the problem?
Anyway, my suggestion is first to figure out, with usual PBE, which
value of l in case.in2 is necessary. Maybe the default l=6 is enough?

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.

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:

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
