FEM structure与FEM fluid 耦合出现的问题
请教各位：我在做铝板和空气耦合模拟阻抗管测量铝板传播损失的时候，在Link后出现以下问题：然后界面跳出，不知是怎么回事，在流体和结构体耦合界面网格大小一样。Building a LINK between Models: 1 and 2

Beginning back substitution 单元过多，计算机内存不足 非常感谢mao的回答，我马上去试试，但是有个疑问，当sysnoise内存不足时，应该提示low memory或者弹出一个框，上面好像是10,000，但是我这个为什么是这种提示呢？恳请高手回答 软件没有你说的好，它不会弹出任何窗口的
