Modelica“解决错误：重载二元运算符不匹配”

Question

我正在使用 Dymola 2014 (Modelica) 并尝试编写模型代码。 我无法“检查”模型，Dymola 给了我以下信息。 使用 Dymola 的人告诉我，这可能是由于缺少“其他”而导致的问题，但我没有看到任何缺失。

每个“if”开头的条件 xxx.activePort 来自代码中的 stateGraph 循环。 请注意，并非所有代码都在这里，但如果需要我可以发布它。 检查只返回那部分代码，所以我认为问题就在这里。 您可能还注意到整个代码包含方程式和算法部分。 下面的代码是方程式部分的一部分。

我是 Modelica 的菜鸟，所以它可能很简单，但我在互联网上没有找到任何可以解决我的问题的东西。

谢谢！

我终于解决了这个问题。

问题是由于一个错误的声明，在代码中系数“j”被声明为一个数组，而这里需要一个标量。
