Webb当选用 SIMPLEC 时，pressure-correction under-relaxation 通常设置为 1，目的之更快地 收敛；当然，有时会因为高的网网格翘曲而出现不稳定，这时，需要使用多个 翘曲修整策略， 使用较为保守的 under-relaxation 值 (最大 0.7)， 或者用 SIMPLE。 ② 当问题牵扯到湍流或者引入了其他物理模型时，如果收敛仅仅取决于压力速度 耦合，SIMPLEC 更易收敛； … Webb8 mars 2024 · Skewness is a measure of asymmetry or distortion of symmetric distribution. It measures the deviation of the given distribution of a random variable from a symmetric distribution, such as normal distribution. A normal distribution is without any skewness, as it is symmetrical on both sides. har value https://slk-tour.com
