* Added a new input format for the list of ions. It is now possible
to group ions (like this [1 2] [5 6]) that are considered
equivalent in the solver. This has required changing the internal
variable 'ion_list' to a dictionary 'ions' which can later be
enhanced by other features (such as specifying ions by element name).
In some MPI implementations the self-consistent run of `sc_dmft.py`
resulted in random freezings. This issue was fixed by polling the
VASP lock file only on the master node.
Also, better exception handling is implemented, allowing all nodes
to exit properly in case of error.
The k-phases turned out to be already included at VASP level.
The previous changes are commented out. However, the dependence
of `ProjectorShell` on `kmesh` and `struct` remains and the tests
are fixed accordingly.
* Fixed obvious bugs:
-- forgotten 'import re'
-- import user script by name from string
-- 'import converter' instead of 'import plovasp...'
* Number of iterations provided by the bash-script now has
an affect.
* Added a possibility to specify an alternative cfg-file
This test suite is based on V d-projectors in SrVO3.
The data have been recalculated to obtain the correct format
of LOCPROJ.
Also, some small but important changes are introduced to
the LOCPROJ parser and class ElectronicStructure.
Specifically, eigenvalues, Fermi-weights, and Fermi level are
now read from LOCPROJ instead of EIGENVAL and DOSCAR.
Besides, LOCPROJ now provides the value of NCDIJ instead of
NSPIN.
Basically, with these changes EIGENVAL and DOSCAR are no longer
needed. Although corresponding parseres will remain in 'vaspio.py'
they will not be used for standard operations.
To make it work one has to create a symlink in 'dft/converters/plovasp'
pointing to the built library 'atm.so'.
Also, one has to use 'from <modulename> import <function>' inside
the test itself to avoid problems with module name substitutions.
The local Hamiltonian is now output after the density matrix.
This is mainly needed for debug purposes. At a later stage the
output should be better formatted and controlled.
At the main SC script 'sc_dmft.py' requires importing a user DMFT
script as a module. Ideally, this should be implemented in a different
way so that the user script imports a function from the self-consistent
script.
Noramlly, the Fermi energy is read from DOSCAR. However, this does
not work in case of a self-consistent calculation in which DOSCAR
is not written between iterations. One of the options is
to modify slightly the output to LOCPROJ and add EFERMI to the
first line.
In the new version of VASP LOCPROJ contains the eigenvalues and
Fermi weights. Also, during a charge self-consistency calculation
the file EIGENVAL is not written at intermediate iterations. It is,
thus, preferential to use LOCPROJ to get the named data.
At the moment, EIGENVAL will still be used if it is complete but
in the future this dependence should be removed completely.
The band indices should be converted to Fortran convention,
i.e. starting from 1, in the output files because the are
used in the density matrix file which is read by a Fortran code.
The format of LOCPROJ has been modified again (in VASP 5.4.2
build from Dec 02, 2015).
Now, there is an additional line before each projector block
providing the spin, k-, and band indices, as well as
eigenvalues and Fermi weights.
