流固耦合的例子!不运行,不知道原因
******************************************************************************************
*本例题是一个流固耦合模态分析的算例;
*
*模型是一个液体中浮体结构的流固耦合频域分析;
*
*流固耦合模态分析的流体必须采用势流体,在建立势流体与结构的耦合模型时如果
*使势流体的节点与相邻结构的节点拟和,ADINA就可以自动建立流固耦合界面,如果节点
*不拟合则需要手动建立流固耦合界面;
*
*对于此类问题应提前根据流体与液体的密度计算好吃水线深度,在建立几何模型时把相互位置建好。

这是adina网站提供的流固耦合的例子,不知道还缺什么东东,不能求解。我用的是adina8.2,望大虾给看看!万分感谢! "CONTROL FILEVERSION=V84"很显然是用adina8.4做的,这种软件一般很难向下兼容的。 所以只能根据命令流自己来操作,或者试着把命令流中的与8.2版本不同的部分去掉

谢谢!
谢谢!本人是老菜,能否提供一点帮助?帮忙修改一下!哪怕给点详细建议也好啊!万分感谢!:handshake 很简单的一个例子,你照着思路做一遍就是的
