在CFD模拟中,特别是使用OpenFOAM这类工具时,time step continuity errors是一个常见的关注点。以下是对这个问题的详细解答: 1. 解释什么是时间步长连续性错误 时间步长连续性错误指的是模拟过程中,连续性方程(质量守恒方程)的违背程度。在理想情况下,所有网格面上的通量之和应等于零,即没有质量流入或流出计算域。...

I am simulating flow in a double cylinder on cone cyclone and so far the iterations are wildly diverging. I am getting very high courant number, time step continuity errors and bounding epsilon. I don't know whether this is problem with my BC's. My mesh has over 60...
我们进一步将全球导航卫星系统 (GNSS) 纳入所提出的 IC-VINS,构建一个以 INS 为中心的 GNSS-视觉惯性导航系统 (IC-GVINS),以在大规模挑战性环境中执行连续、稳健和准确的定位。 Conventionally, the state estimation problem in VINS is addressed through filtering [8], [9], [10], [11]. However, we h...
several interferograms with temporal/ spatial baselines larger than the thresholds are also included to guaran- tee temporal continuity for sbas time-series analysis (fig. 2). the doris software (kampes, hanssen, they are xian high-tech zone, xian qujiang new zone (qj hereinafter), chanba ...
各位前辈,在输出的 log 里面,time step continuity error 是什么意思啊? GAMG: Solving for p, Initial residual = 1.6635216e-07, Final residual = 7.1234503e-08, No Iterations 2 time step continuity errors : sum local = 1.3428446e-12, global…
