[Wien] Error in LAPW0 (For volume change of +6%)

2012-04-17 Thread Mojtaba Zareii
Hi dear wien2k users I want to simulate the LaNi5H7 compound. To do this, I first found the optimum RKmax equal to 4.5. Then, For finding the equilibrium volume, I used "Optimize Prog." (Gmax=18, MT radii of 2.35, 1.79 and 0.9 a.u. for La, Ni, H atoms respectively.). The variation of volume was set

Why would you change RKmax when a problem occurs in lapw0 ?? Increase the FFT-grid in case.in0 (either the 3 numbers explicitly or the multiplicative factor). Most likely you should also rerun the previous volumes (starting from the converged results) with the modified case.in0 file. Am 17.04.2
