Dear Alaska,

Right now, the density is written by the process 0, and read by all. 
This assumes that
files are shared.
Writing is done in the routine: 21drive/outscfcv.F90.
I would try the modification, which will allow all processes to write:

=== modified file 'src/21drive/outscfcv.F90'

  if (prtden/=0 .or. prtpot>0 .or. prtgeo>0 .or. prt1dm>0 .or. prtstm>0 
.or. &

But, in the future, this should be governed by a variable.
