[交流] 【求助】fluent模拟气固流化床采用欧拉模型并行计算出现问题 已有7人参与

如题,Domain Extents:
   x-coordinate: min (m) = -1.504056e+000, max (m) = 1.504056e+000
   y-coordinate: min (m) = -1.504056e+000, max (m) = 1.504056e+000
   z-coordinate: min (m) = -3.954906e+000, max (m) = 4.000000e+000

迭代 0.001s间隔。每步迭代 23次, ( courant数=0.01)  在迭代了3步后出现问题如下,一直很困惑,好像是网格的问题,但是不知道如何解决啊

你把迭代时间步长缩小些试试 而且是缩小很多 0.001s有点太大了

谢谢你,我倒是没事过调节步长值,但是我是重新画了网格就可以了,减少画网格的分区

在PHASE中可以定义颗粒直径啊

那里面不是只能定义成常数么?我想要定义为一个粒度区间怎么实现呢?
