Using GULP with ShengBTE
Version 5.0 of the General Utility Lattice Program (GULP) has support for creating ShengBTE inputs. Specifically, the program can create CONTROL, FORCE_CONSTANTS_2ND and FORCE_CONSTANTS_3RD files for thermal conductivity calculations based on semiempirical potentials. GULP can be downloaded from: under the terms of its own license. Please note that the ShengBTE team is not affiliated with GULP.http://gulp.curtin.edu.au/gulp/ 
thirdorder.py v1.1.1
thirdorder.py v1.1.1 has been released. This is a minor bugfix release to solve a problem with the handling of negative coordinates in the ESPRESSO script. 
thirdorder.py v1.1.0 released
thirdorder.py v1.1.0 is now available from the usual locations, including the Downloads section. This release adds important new features, namely CASTEP and Python 3 support.

almaBTE v1.1 released
Version 1.1 of almaBTE has been released and is freely available from www.almabte.eu AlmaBTE is a software package that solves the space and timedependent Boltzmann transport equation for phonons, using only abinitio
calculated quantities as inputs. The software can currently model phonon
transport in bulk crystals and alloys, thin films, superlattices,
and multiscale structures with size features in the nmμm range. Among
other quantities, the program can output thermal conductances and
effective thermal conductivities, spaceresolved average temperature
profiles, and heatcurrent distributions resolved in frequency and
space.Another interesting development is the almaBTE database of force constants, with publicationquality sets of harmonic and anharmonic inputs for many semiconductors of theoretical and industrial interest. We encourage ShengBTE users to try almaBTE and to contribute to its development. 
ShengBTE v1.1.0
Version 1.1.0 of ShengBTE has been released and can be obtained from the Downloads section. New features include the ability to study several temperatures in the same run and compute weighted phase space volumes. A couple of issues with symmetrization have been fixed. Due to the many changes to the output formats introduced by this new version, users are encouraged to read the documentation (in file README.md). 
ShengBTE v1.0.2
Version v1.0.2 can now be obtained from the Downloads section. This release improves the numerical stability of the nonanalytic correction to the dynamical matrix and of the iterative solution to the BTE. It also ensures better compliance of the conductivity tensor with the symmetries of the system. 
ShengBTE v1.0.1 and thirdorder.py v1.0.2
ShengBTE v1.0.1 and thirdorder.py v1.0.2 are now available from the usual locations, including the Downloads section. The new release of ShengBTE fixes a bug in the calculation of the projected density of states. With respect to thirdorder.py, the main changes are:

ShengBTE v1.0.0
Version 1.0.0 of ShengBTE comes with a few new features:
v1.0.0 also fixes an important bug. Acoustic frequencies at Gamma were assumed to be exactly 0 in the scattering rate calculations, but not actually set to zero. This caused quite a lot of trouble for certain crystal structures. Moreover, the documentation has been rewritten in Markdown to make it simpler to read from a textonly terminal. The new release can be obtained from the Downloads section. 
ShengBTE v0.9.16 and thirdorder.py v1.0.1
ShengBTE v0.9.16 and thirdorder.py v1.0.1 are now available from the Downloads section. v1.0.1 of thirdorder.py brings an overhaul of its core, now written in Cython. No Fortran compiler is needed to build the shared library now. Since BLAS used to be source of most linking problems, we hope that this change makes compilation easier. Please refer to README.md for details. The main change in ShengBTE is the treatment of degenerate modes, whose group velocities are now properly symmetrized. Some new files have been added to the output. As usual, some bugs have been ironed out here and there.
