Re: [SIESTA-L] how to increase accuracy of bulk modulus calculations?

2007-03-01 Thread Oleksandr Voznyy
Do you have a cubic cell? Don't do VariableCell then, it destroys symmetry. (check the forces on atoms to be 0) If you know the exact symmetry of the cell (relative positions of atoms in the cell) then adjust only lattice constant. Then the effect of pressure in all direction will change the la

[SIESTA-L] how to increase accuracy of bulk modulus calculations?

2007-03-01 Thread Yurko Natanzon
Dear siesters, I'm trying to calculate bulk modulus and cannot get reasonable results. I start from some unrelaxed cubic structure and run VariableCell optimization. I obtain some relaxed structure with reasonable lattice constant. Then I repeat the same calculations but set nonzero value of MD.Ta

hello siesta user, i have some calculations on lo-to splitting. In the manual the version for lo-to splitting is not with vibra in siesta so how can i get this package. also i mail to Tom Archer, but no responce... plz guide me

Re: [SIESTA-L] LDOS problems

2007-03-01 Thread Simon Dubois
Hi Kun Tao, Maybe your confusion comes from the term "density" which means "density by unit of energy" in one case (DOS), and "density by unit of volume" in the other one (LDOS). Indeed, the DOS is the density of state by unit of energy. In this case, you dont have any integration along the e

[SIESTA-L] LDOS problems

2007-03-01 Thread Tao K
Dear Siesta user, Could you tell me the physical meaning of the Local Density Of State? What is the difference between the LDOS and DOS? When we want to get the LDOS , we also integrate it between two given energies (similar to that of the DOS). And what can we get for the LDOS? Thank you in adva

hello siesta user, can you tell me where in siesta-2.0.1, i find the patch files for siesta-2.0 In siesta website it is written that patch files for siesta2.0 is in siesta2.0.1. And one more thing is this new version is ready to use in parallel (mpi) thanks
