Dear All,

     I am currently doing some Co cluster calculation, but the calculation is taking a lot of time. For VASP we can reduce the computational time by calculating the charge density self-consistently using a lower number of k point and then fixing the charge density and then performing further calculation using higher number of k-points and solving the problem NON-self-consistently. We can do this since the charge density converges to an accurate enough value for lower number of K points. This was we can greatly reduce the amount of time required for computation. I was wondering since CASTEP and VASP has the same origin, is it possible to employ similar methods in CASTEP. Thanks a lot in advance
