论文摘要
为了模拟相对论核冲突中创建的问题的扩展,使用了3+1个维度的代码,我们正在开发一个新的。为了基于此类代码,经常使用SOD的冲击管。一个密切相关的问题是气体向真空的一维膨胀。在本文中,我们通过平滑的粒子方法在经典和相对上研究此问题,并测试各种技术以提高溶液的精度和速度。
To simulate the expansion of the matter created in relativistic nuclear collisions, codes in 3+1 dimensions are used and we are developing a new one. To benchmark such codes, the Sod's shock tube is often used. A closely related problem is the one-dimensional expansion of a gas into vacuum. In this paper, we study this problem classically and relativistically with the Smoothed Particle Method and test various techniques to improve the precision and speed of the solution.
