Please enter a valid KIM Model extended-ID: Please enter the species symbol (e.g. Si, Au, Al, etc.): Please enter the atomic mass of the species (g/mol): Please enter the lattice type (bcc, fcc, sc, or diamond): Please specify a lattice constant (referred to as a_0 below) in meters about which the energy will be computed (This will usually be the equilibrium lattice constant. Most of the volumes sampled will be about this lattice constant.): Please specify the smallest lattice spacing (referred to as a_min below) at which to compute the energy, expressed as a fraction of a_0 (for example, if you wish for a_min to be equal to 0.8*a_0, please specify 0.8 for this value): Please specify the largest lattice spacing (referred to as a_max below) at which to compute the energy, expressed as a multiple of a_0 (for example, if you wish for a_max to be equal to 1.5*a_0, please specify 1.5 for this value): Please enter the number of sample lattice spacings to compute which are >= a_min and < a_0 (one of these sample lattice spacings will be equal to a_min): Please enter the number of sample lattice spacings to compute which are > a_0 and <= a_max (one of these sample lattice spacings will be equal to a_max): Please enter a value of the lower sample spacing parameter (see README.txt for more details): Please enter a value of the upper sample spacing parameter (see README.txt for more details):
