TRANSFORM库v0.4与OpenModelica v1.22.3兼容性咨询及测试报错

测试环境 #

• 操作系统：Windows 10 22H2
• TRANSFORM库版本：0.4
• OpenModelica版本：v1.22.3-64bit

问题描述 #

我想确认TRANSFORM库当前是否兼容OpenModelica，以及具体兼容程度。在尝试运行TRANSFORM流体包中的PumpingSystem示例（模型结构与MSL中的对应示例一致，但使用TRANSFORM组件）时，出现了一系列翻译错误，具体报错信息如下：

问题分析 #

这些报错的核心是数组组件的非数组修改未使用each关键字。在Modelica语法中，当修改数组类型的属性（如min、max、stateSelect）时，若要给数组的每个元素赋予相同值，必须使用each关键字明确声明。TRANSFORM库的这些基础组件代码中缺少该关键字，导致OpenModelica的翻译器无法正确解析。

兼容性结论 #

当前TRANSFORM 0.4版本与OpenModelica 1.22.3-64bit不兼容，至少流体包的核心组件存在语法兼容性问题，无法通过OpenModelica的翻译环节。这类问题通常是库开发时针对其他仿真器（如Dymola）编写，未严格遵循Modelica标准语法或适配OpenModelica的解析规则导致的。
