WebOct 17, 2024 · The basis set, as defined by the energy cutoff value, is one of the most important parameters that determine the accuracy (and the cost) of a CASTEP calculation. The easiest way to set this value is by using the Energy cutoff option on the Electronic tab of the Calculation dialog. If you use this method, the cutoff value which is optimal for a ... WebApr 30, 2024 · Or smaller cutoff energies will give a larger range of deviation from the ‘true value’. The exact pattern may be dependent on the indicator of convergence we choose. The practical implementation of cutoff energy in CASTEP codes will affect the pattern as well. But the tendency could be general for cutoff energy’s convergence path.
