ANSYS流固耦合，运行时出现错误（附命令流）

我用的是FSI solver 法，用 SF 及 FSIN 在流体结构界面作两次标记，一次是在界面的流体侧，一次是在界面的固体侧，
但运行时总是出现"ERROR: NO FSIN boundary conditions are defined in the modal."这样的错误。不知道其原因，希望大家有谁明白，解析一下。谢谢！这是流体、固体部分的命令流。

错误提示不是说的很清楚吗。

什么很清楚呀？

这不是定义了吗？
还需怎样定义呀

此问题解决了

谢谢大家的关注，此问题解决了，但又有了新的问题，没事一步一步解决吧

klh111 发表于 2009-3-6 18:57:35

怎么解决的啊？能共享下您的经验吗？

weihua515 发表于 2009-3-6 21:17:28

可否推荐下流固耦合方面的书和资料,最近正要做

yuguoxingqin 发表于 2009-10-30 08:58:50

我发现，现在怎么都是这样，问题怎么解决的都不传上来看看！
