Dear current and future feram users,
I released feram-0.19.09.tar.xz from
http://sourceforge.net/projects/loto/files/feram/ .
"feram" is a fast molecular dynamics (MD) simulator
for bulk and thin-film ferroelectrics. Its homepage is
http://loto.sourceforge.net/feram/ .
From this version 0.19.09, acoustic displacements will
be written in .coord files. For more details,
see src/coord_module.F, src/optimize-inho-strain.F, and
doc/acoustic-displacements.pdf.
The version 0.19.08 contains bug-fixed src/coord_module.F.
With this fix, feram will write the whole system,
not half of the system, into .coord files, when
bulk_or_film = 'film' or 'epit'. Now, you can perform
cooling-down and heating-up simulations of films.
See src/17example-PbTiO3-100-900K/coolflm.sh
and src/17example-PbTiO3-100-900K/heatflm.sh.
From the version 0.19.07, a new tag "distribution_directory"
is introduced to control .distribution and .distribution3d
output files. You can use distribution3d2ppm command
for visualization of 3-dimensional distribution of dipole
vector u. See README.en, README.ja, average_module.F
and distribution3d2ppm.F.
From the version 0.19.06, a new tag "coord_directory" is
introduced. It controls the directory into which .coord files
will be stored.
From the version 0.19.05, FFTW_MEASURE is used for the FFTW
Planner Flag instead of FFTW_PATIENT. For more details,
$ grep FFTW_MEASURE src/coord_module.F
and see http://www.fftw.org/doc/Planner-Flags.html .
Use fft_check to boost up your calculations.
From the version 0.19.05, You cannot compile feram with
OFORT90 (Hitachi Fortran). Use xlf90_r (IBM XL Fortran)
for SR16000.
From the version 0.19.04, feram tries to import
'wisdom' file from current directory or /etc/fftw/wisdom.
Enjoy,
