Abstract

Initial-boundary value problem for linear acoustics has been solved in two spatial dimensions. It has been assumed that the initial acoustic field consists of two Gaussian distributions. Dirichlet boundary conditions with zero acoustic pressure at the boundaries have been imposed. The solution has been obtained with the help of a split-operator technique which resulted in a cellular automaton with uncountably many internal states. To visualize the results, the Python library matplotlib has been employed. It has been shown that attractive graphical output results in both the transient and stationary regimes. The visualization effects are similar to, but different from, the well-known quantum-mechanical carpets.

声地毯

线性声学的初边值问题在二维空间上得到了求解。假设初始声场由两个高斯分布组成。给出了边界处声压为零的狄利克雷边界条件。利用分裂算子技术得到了具有不可数内态的元胞自动机的解。为了可视化结果，使用了Python库matplotlib。结果表明，有吸引力的图形输出在瞬态和稳态状态下都是有效的。可视化效果与众所周知的量子力学地毯相似，但又不同。

期刊介绍： Machine GRAPHICS & VISION (MGV) is a refereed international journal, published quarterly, providing a scientific exchange forum and an authoritative source of information in the field of, in general, pictorial information exchange between computers and their environment, including applications of visual and graphical computer systems. The journal concentrates on theoretical and computational models underlying computer generated, analysed, or otherwise processed imagery, in particular: - image processing - scene analysis, modeling, and understanding - machine vision - pattern matching and pattern recognition - image synthesis, including three-dimensional imaging and solid modeling
