沿空掘巷采空区接触面建立后使用attach还是merge连接问题

狒狒007

在采空区顶底板建立接触面之后。使用attach还是merge连接模型，之前用attach连接 出现了云图不连续，而采用merge连接又出现了restore 计算保存文件错误 导入tecplot时 出现导入不进去的问题

这是在采空区建立接触面之后用attach 连接模型后计算完毕的云图

这是用merge连接模型之后计算完毕  再restore 出现的问题 关键是不能导入tecplot进行后处理

上面是采用merge命令进行连接模型的命令流

狒狒007

有木有做沿空掘巷之类模拟的，请教一下

wqq8889

建立接触面之后merge和attach都不能用，不然你的接触面就没有用了

dongxx0221

直接拼接建模，如果网格尺寸是整数倍，不需要attach或merge。attach会使inter失效。attach和merge选一个使用。
