OMNET ++中的多个连接

问题描述

我是Omnet ++的新手。我试图同时从一个节点（一个出门）向多个节点（多个入门）发送消息。

但是，当我运行omnet.ini时，它显示错误：“访问大小为0的向量gate out []时超出范围”。你能帮我吗？此代码有什么问题？我猜想k在send（msg，“ out”，k）方法中是错误的。

   simple Test

   {
    gates:
    input in[];
    output out[];
  }

  network testNetwork
  {
   @display("bgb=764,369");
   submodules:
    computer0: Test {
        @display("p=55,22");
    }
    computer1: Test {
        @display("p=141,36");
    }
    computer2: Test {
        @display("p=233,22");
    }
    computer3: Test {
        @display("p=308,24");
    }
    

     connections:
    computer1.out++ --> computer0.in++;
    computer1.out++ --> computer2.in++;
    computer1.out++ --> computer3.in++;
  }
