求助：fsi中设置的问题

1• Always check the solutions obtained so far to see if they are
physically reasonable. Try to exclude possibilities of errors in
input data.
2• Reduce the stress relaxation factor if it is not too small.
3• Reduce the displacement relaxation factor if it is not too small.
4• It is generally suggested that tolerances in fluid and solid models
are smaller than the tolerance for FSI convergence tolerance. If
you have not done it, make some adjusts.
5• Perform direct computing rather than the iterative computing.

这是流体里面3069错误
其中  stress relaxation factor 和 dispalcement relaxation factor分别在什么地方设置啊
另外第四点中那个fsi convergence tolerance在哪里设置啊
第五点又是在哪啊

请求帮忙。
感激。

ls看过fsi分析的帮助手册？这个是最基本的知识俄
