polymathic-ai/euler_multi_quadrants_openBC

该数据集名为Euler Multi-quadrants - Riemann problems，涉及可压缩、无粘性流体的多象限Riemann问题。数据集分为两个版本：`euler_multi_quadrants_openBC`（开放边界条件）和`euler_multi_quadrants_periodicBC`（周期性边界条件）。数据描述为：从象限中的分段常数初始数据开始的不同气体的演化。演化过程可能产生激波、稀疏波、接触间断、彼此之间的相互作用以及域壁。数据集包含100个时间步长的512x512图像，字段包括密度（标量场）、能量（标量场）、压力（标量场）和动量（矢量场）。总共有10,000条轨迹，估计大小为5.17 TB。数据生成使用了Clawpack (AMRClaw)软件，硬件为Icelake节点，双精度。

The dataset is named Euler Multi-quadrants - Riemann problems and deals with multi-quadrant Riemann problems for compressible, inviscid fluid. The dataset is distributed in two separate datasets: `euler_multi_quadrants_openBC` with open boundary conditions and `euler_multi_quadrants_periodicBC` with periodic boundary conditions. One line description of the data: Evolution of different gases starting with piecewise constant initial data in quadrants. Longer description: The evolution can give rise to shocks, rarefaction waves, contact discontinuities, interaction with each other and domain walls. The dataset includes 100 timesteps of 512x512 images, with fields available: density (scalar field), energy (scalar field), pressure (scalar field), momentum (vector field). There are 10,000 trajectories in total, with an estimated size of 5.17 TB. The data was generated using Clawpack (AMRClaw) software, on Icelake nodes with double precision.
