Numerical diffusion — is a difficulty with computer simulations of continua (such as fluids) wherein the simulated medium exhibits a higher diffusivity than the true medium. This phenomenon can be particularly egregious when the system should not be diffusive at all,… … Wikipedia
Numerical resistivity — is a problem in computer simulations of ideal magnetohydrodynamics (MHD). It is a form of numerical diffusion. In near ideal MHD systems, the magnetic field can diffuse only very slowly through the plasma or fluid of the system; it is rate… … Wikipedia
Numerical model of the Solar System — A numerical model of the Solar System is a set of mathematical equations, which, when solved, give the approximate positions of the planets as a function of time. Attempts to create such a model established the more general field of celestial… … Wikipedia
