Saula (fictional planet) Saula (fictional planet) Saula is a fictional planet described in ""An Attempt to Escape" ("Попытка к бегству")" by Boris and Arkady Strugatsky. This planet is a part of the so-called Noon Universe and presents a world in an early feudalistic stage (opposite to e.g. late feudalism of Arkanar). The planet was named after Saul (Savel) Repnin, one of the space explorers who discovered it in 2141 AD. Saula is the second planet (out of four) of EN-7031 solar system, about one and a half times further from its sun than Earth is from ours. The day and night cycle on
Closest point method surrounding the surface for efficient computational purposes. formula_13 where formula_14 is the bandwidth. Using initial profile formula_15 leads to the solution formula_16 for the heat equation. Forward Euler time-stepping is used with relation formula_17 and degree-four interpolation polynomials for the interpolations. Second-order centered differences are used for the spatial discretization. The CPM results in the expected second order error in the solution formula_18. The closest point method can be applied to various PDEs on surfaces. Reaction–diffusion problems on point clouds [RD], eigenvalue problems [EV], and level set equations [LS] are a few examples.
