modelica - 无法为 Dymola 中的所有匹配选项添加选择器

Question

我正在关注 Claytex 的教程 https://www.claytex.com/blog/dymola-basics-8-dymola-model-inheritance/在部分和扩展模型上。我能够从父(部分)模型创建继承(扩展)模型，并且它允许我在兄弟类之间进行更改。但是，我想为所有兄弟类添加框选择器，如教程中所示

这是我的代码

型号“a”

partial model a
  Modelica.Thermal.HeatTransfer.Interfaces.HeatPort_a port_a annotation (
      Placement(transformation(rotation=0, extent={{-110,-10},{-90,10}})));
  Modelica.Thermal.HeatTransfer.Interfaces.HeatPort_b port_b annotation (
      Placement(transformation(rotation=0, extent={{90,-10},{110,10}})));
  annotation (uses(Modelica(version="3.2.3")), Icon(graphics={Text(
          extent={{-100,102},{98,-98}},
          lineColor={28,108,200},
          textString="A")}));
end a;

型号“b”

model b
  extends a;

  Modelica.Thermal.HeatTransfer.Components.ThermalResistor thermalResistor(R=3)
    annotation (Placement(transformation(extent={{-10,-10},{10,10}})));

equation 
  connect(port_a, thermalResistor.port_a)
    annotation (Line(points={{-100,0},{-10,0}}, color={191,0,0}));
  connect(port_b, thermalResistor.port_b)
    annotation (Line(points={{100,0},{10,0}}, color={191,0,0}));


  annotation (Icon(graphics={Text(
          extent={{26,96},{98,12}},
          lineColor={28,108,200},
          textString="B")}));
end b;

模型“装配体”

model assembly
  Modelica.Thermal.HeatTransfer.Sources.FixedTemperature fixedTemperature(T=274.15)
    annotation (Placement(transformation(extent={{-60,40},{-40,60}})));
  Modelica.Thermal.HeatTransfer.Sources.FixedTemperature fixedTemperature1(T=275.15)
    annotation (Placement(transformation(extent={{40,40},{20,60}})));
  replaceable b a1 constrainedby a annotation (choicesAllMatching=true, Placement(transformation(extent={
            {-20,40},{0,60}})));
equation 
  connect(fixedTemperature.port, a1.port_a)
    annotation (Line(points={{-40,50},{-20,50}}, color={191,0,0}));
  connect(a1.port_b, fixedTemperature1.port)
    annotation (Line(points={{0,50},{20,50}}, color={191,0,0}));
  annotation (uses(Modelica(version="3.2.3")));
end assembly;

如果有人能指出我的实现与教程的不同之处，我将不胜感激。提前致谢。

Answer 1

这应该在 Dymola 中本身起作用(假设所有类都是公共(public)的)，但是要获取框选择器，您需要在 assemble 图的背景中单击，或者使用它创建一个 TopModel，如教程，然后打开 assemble1

的参数对话框

model TopModel
  assembly assembly1
    annotation (Placement(transformation(extent={{-40,20},{-20,40}})));
  annotation (Icon(coordinateSystem(preserveAspectRatio=false)), Diagram(
        coordinateSystem(preserveAspectRatio=false)));
end TopModel;

此外，部分类会从选择器中过滤掉，因此您只能在其中获得 b ，除非您还添加:

model c
  extends a;

  Modelica.Thermal.HeatTransfer.Components.ThermalResistor thermalResistor(R=3)
    annotation (Placement(transformation(extent={{-10,-10},{10,10}})));

equation 
  connect(port_a, thermalResistor.port_a)
    annotation (Line(points={{-100,0},{-10,0}}, color={191,0,0}));
  connect(port_b, thermalResistor.port_b)
    annotation (Line(points={{100,0},{10,0}}, color={191,0,0}));

  annotation (Icon(graphics={Text(
          extent={{26,96},{98,12}},
          lineColor={28,108,200},
          textString="C")}));
end c;

我将所有这些类都包含在一个包 P 中。请注意，第一次打开选择器可能需要几秒钟的时间。
