错误(3817)

错误信息

虚拟连接图多根连通分量转生成树错误: %1!s!.

产生原因

虚拟连接图中存在多根且无法通过打断边分离多根.

解决方法

删除被连接的根节点或唯一根节点的根节点属性,或者删除根节点之间的连接.

示例

model _3817_VirtualConnect_MultiRoot_Translate
  record Orientation
    Real T;   
    function equalityConstraint
      input Orientation R1;
      input Orientation R2;
      output Real residue;
    algorithm 
      residue := R1.T + R2.T;
    end equalityConstraint;
  end Orientation;   
  connector Frame
    Orientation R;
  end Frame;  
  Frame a(R(T = 1));
  Frame b;
  Frame c;
equation 
  Connections.root(a.R);
  Connections.root(b.R);
  Connections.branch(a.R, b.R);  // Error: 3817 两个根节点之间存在不可打断边
  connect(b, c);
end _3817_VirtualConnect_MultiRoot_Translate;
