SYSNOISE计算时出错
我计算的模型比较大,开始计算一段时间后,它总要由于错误自动停止计算,下面是Echo里面的信息,我读不懂,请教一下大家是什么原因?

请问高手 该如何解决? .log的其他信息有吗??贴出来方便大家帮你排查 模型规模太大导致的,在分块计算的时候无法处理。Beginning matrix decomposition
Block #1
建议把BE的网格规模缩小
或者提高内存空间 请教一下规模多少的限制怎么算,和内存的关系是怎样? 同意chourhy兄的意见,我将模型改小了,确实再没有上述错误发生。谢谢!
可是内存空间SYSNOISE最大只能占用到500,已经无法再提高了:@L 我也出现类似的问题

到这个位置的时候,就停住没有下文了,SCL history 里面是空的,没有文字
主界面打不开,或者打开了也是一片蓝色,鼠标变成小时钟的样子。但是LOG中没有提示出现error啊,不知道是不是和一楼同样的问题。但是我必须要计算这个频率,网格不能画的大,现在这个网格密度正好可以计算1K。
我的模型是比较大,但是实际情况就是这样的,也没有办法改啊
不知道这种情况到底怎么办呢 回复 6 # yesangle 的帖子
我刚刚也出现了这个问题,不知道楼上是怎么解决的啊?
