请求帮助,在一篇文献中看到这样的求解算法,但不知道怎么实现,有知道的还望指点一下。文献原话为“. Although the steady-state behavior is of interest,the unsteady simulations are performed and the results are time averaged in order to obtain the steady-state flow characteristics.This was found to provide both better accuracy and numerical stability”,这是用fluent进行计算的,我的理解是进行瞬态计算,然后结果求时间平均,但这怎么实现呢?
自问自答吧,发现在fluent瞬时求解过程中的Solution/run calculation选项里面有Data Sampling for Time Statistics选项有这个功能,可以通过Sampling Options 选择需要取样的参量,参量可以是fluent自带的也可以是通过自带参量间相互运算后的结果,这个参量需要通过Define/Custom field functions 进行定义。
