How to create gui (graphic user interface) for standalong binary executable file

Question

I have a model in Modelica language (platform: Dymola). Dymola creates a binary file of model during compiling/translation (dymosim.exe). If binary code export licence is available then a binary file which is standalone representative of original dymola model is created. This can be run on any computer without Dymola licence.

Now, My question is how can I create Gui for around this executable file with following requirements:- 1. It should be able to change in some input parameter values. 2. It should be able to get some output parameter values.

Now as background:- dymosim.exe takes parameter values as input from text file (dsin.txt) and writes output in another text file (dsres.txt)

Specifically, if one has such binary executable which takes input from a text file and writes output in specific format (of which rules are known) to another text file; then what are some tools to create gui for it?

Answer 1

Look into Dymola's embedded server support (DDE/OPC). Since you are using dymosim.exe, I believe you are using Windows so Dymola's restriction on only Visual Studio 32-bit code for embedded servers will be acceptable. (Most Modelica tools have similar embedded servers, but I don't think they are compatible.)

Answer 2

Dymola dymosim.exe将其时间序列结果导出为*.mat个文件，您应该能够在GUI中找到处理*.mat格式的工具/库。

此外，dsin.txt有自己的格式，您可以先尝试理解它（尝试查找其注释），然后解析它，它不是一个包含随机字符串和数字列的文本文件。

Answer 3

在协同仿真模式中使用FMI标准值得考虑，这意味着包含了求解器。 Dymola允许将模型导出为FMU包（在Windows平台中它是带有一些元数据的单个DLL，在Linux平台中它是.SO库）并提供这些功能值得你做的步骤：

• fmiSetReal（）将设置参数值
• fmiDoStep（）
• fmiGetReal（）将获得变量值

您可以直接调用这些函数，只需解压缩FMU包并在其中找到DLL并将其直接链接到您的应用程序。 或者推荐的方式（我们在我们的应用程序中完成）：使用FMI Library提供与FMU包交互的通用C API，并以您需要的方式控制时间结构。
