奇怪的现象-搅拌器负压-3

今天又从以下几点进行了测试:

1、旋转叶轮设置成移动壁面  无改变

2、更换叶轮模型 无改变

3、改成空气 无改变

4、初始化速度改成0 无改变

5、更改湍流模型 无改变

6、网格从多面体改成四面体 无改变

---------------------------

虽然无进展,但是也得到了一些规律:

1、进口速度越快 单个时间步收敛越快 当然动画中看变化也快

2、旋转速度慢 单个时间步收敛快

等待进一步研究

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
