We call it as 2D-optimize. The new package is compatible with the highly accurate all-electron full-potential (linearized) augmented plane-wave plus local orbital [FP-(L)APW+lo] method implemented in WIEN2k code. This package is available with WIEN2k code. We have performed a convenient volume and c/a structure optimization by using 2D-optimize package. First, we find the best value of c/a and therefore the energy for each volume, and then for those volumes and energies the equation of state (EOS) will obtained, and after that the value of c/a calculates within optimal volume. We have done 1D and 2D search of EOS for MnAs and Mg within PBE functional and compared the results with experimental data, the results of 2D search for EOS are better than 1D search of EOS. The cell parameters and the bulk modulus of 20 hexagonal structure compounds were calculated using the new package and compared with the experimental data. 2013-02-16T03:17:56Z 2013-02-16T03:17:56Z 2013-04-05 Article Journal of Alloys and Compounds, vol. 55, 2013, pages 362-366 0925-8388 http://www.sciencedirect.com/science/article/pii/S0925838812022475 http://hdl.handle.net/123456789/23604 en Elsevier B.V.
