A Framework for Initial Transient Detection and Statistical Assessment of Convergence in CFD Simulations
计算流体动力学模拟中的初始暂态检测与收敛统计评估
Time series data often contain initial transient periods before reaching a stable state, posing challenges in analysis and interpretation. In this paper, we propose a novel approach to detect and estimate the end of the initial transient in time series data. Our method leverages the reversal mean standard error (RMSE) as a metric for assessing the stability of the data. Additionally, we employ fractional filtering techniques to enhance the detection accuracy by filtering out…
