刚开始迭代时,遇到absolute pressure limited on zone 2
我算的是叶轮机械的流场,8个靜叶加配合上12个动叶,总网格数大约400万多,我的机器是8G内存,I5的处理器,四核的,初始化后,我开始迭代,一步也迭代不下去,网格质量应该没啥问题啊,我在Gambit中建模时都检查过了。出现了下列错误:absolute pressure limited to 1.000000e+000 in 1081046 cells on zone 2
temperature limited to 1.000000e+000 in 1081046 cells on zone 2

,求各位大侠不吝赐教啊,论文做不下去了,查了好多资料,这个问题解决不了,着急啊!!!! 跪求回复啊 回复 2 # skgk-qqq 的帖子
你说网格质量没问题。怎么判断的?简单check grid是不够的。
我以前回答过一些问题,有一篇帖子做了个小结,你可以参考一下,看看有没有什么帮助:
http://forum.vibunion.com/thread-109619-1-1.html 我不是简单check了啊,在Gambit中将网格检查了,好的,谢谢你,我刚才查看了那个链接,我会按照那个要求,再试试。
