资源简介:
Raw data to replicate the tabulated results included as supplementary material in the accompanying article. Benchmark problems: Zalesak, vortex-in-a-vox, star-shaped droplet and Smolarkiewicz flow. Inputs: spatial adaptation strategy (isotropic/anisotropic), minimum mesh size (1/32 ... 1/1024), maximum mesh size (1/2 ... 1/16), number of marker particles (Np=0,1e4,5e4,1e5), and level set reinitialization procedure (every 2 steps/off). Outputs: errors (L1,L2), area loss (percentage) and maximum area loss (percentage), number of elements, number of nodes, wall-clock time, wall-clock time spent in meshing (and percentage), maximum memory demand (in kB and MB). Comments: *Zalesak slotted cylinder: all results are after 100 full rotations. Time step size dt=1/100. *Vortex: refers to circular droplet in single vortex flow. Periodic version with Tp=8, and non-periodic version with final time t=8. Time step size dt=1/100. *StarShaped: refers to five-pointed, star-shaped droplet in single vortex flow. Periodic version with Tp=8, and non-periodic version with final time t=8. Time step size dt=1/100. *Smolarkiewicz: refers to Smolarkiewicz flow. Periodic version with Tp=2Pc, and non-periodic version with final time t=5Pc, with Pc=25/(16pi). Time step size dt=1/100Pc.
本数据集用于复现配套学术论文中作为补充材料收录的制表结果。基准测试集包含以下问题:Zalesak槽圆柱(Zalesak slotted cylinder)、体素内涡旋(vortex-in-a-vox)、星形液滴(star-shaped droplet)与斯莫拉列维奇流(Smolarkiewicz flow)。
输入参数包括:空间自适应策略(spatial adaptation strategy),可选各向同性(isotropic)或各向异性(anisotropic);最小网格尺寸,取值范围为1/32 至 1/1024;最大网格尺寸,取值范围为1/2 至 1/16;标记粒子(marker particles)数量,可选取值为Np=0、1e4、5e4、1e5;以及水平集重初始化程序(level set reinitialization procedure),可选设置为每2步执行一次或关闭。
输出指标包括:误差(L1、L2范数)、面积损失率与最大面积损失率、单元总数、节点总数、墙钟耗时、网格划分耗时(及占总耗时的百分比)、最大内存需求(单位为kB与MB)。
备注说明:
* Zalesak槽圆柱:所有结果均为100次完整旋转后的计算结果,时间步长dt=1/100。
* 体素内涡旋:指代单涡旋流场中的圆形液滴,分为周期版本(周期Tp=8)与非周期版本(终止时刻t=8),时间步长dt=1/100。
* 星形液滴:指代单涡旋流场中的五角星状星形液滴,分为周期版本(周期Tp=8)与非周期版本(终止时刻t=8),时间步长dt=1/100。
* 斯莫拉列维奇流:指代Smolarkiewicz流,分为周期版本(周期Tp=2Pc)与非周期版本(终止时刻t=5Pc,其中Pc=25/(16π)),时间步长dt=1/(100Pc)。
