[Wien] Lattice Thermal Conductivity and Phonon dispersion
Hi every one, I am interested to find out the phonon dispersion and the lattice thermal conductivity using WIEN2k. I have used phonopy code to calculate the dispersion curve but too many errors have been encountered.Even if I am successful in getting the dispersion curve how can I get the lattice thermal conductivity from that ?? Kindly guide me.

[Wien] Phonon Density of States
Hi everyone. I am using WIEN2k code for my calculations for sometime now. The experts of WIEN2k kindly guide me regarding the following queries: 1- What is the information we can get from the phonon density of states? Can we get to know about the stability of a material? 2- How can I get the phonon density of states using WIEN2k? 3- Is there any other package need to be installed? If so kindly guide me to the installation and usage of that. Thanking you in anticipation. Waiting for your helpful comments.

[Wien] Elastic Constants of Trigonal Systems
I am new to WIEN2k. I am in need for help from the experts in finding the elastic constants. I am interested in finding out the elastic constants of trigonal systems by WIEN2k. There are packages available for hexagonal, tetragonal, orthorhombic and cubic systems. What should I do for Trigonal systems. I have used the hexagonal package but I have obtained quite large values for one constant and very large negative values for another. One of the plot also shows oscillations and it is not correct. Kindly guide me.
