Modelica is primarily used for modeling and simulation of physical systems and does not have built-in commands to directly print text like “Hello World!” as you would in languages such as C, Python, or Java. However, if you want to display a message using the ModelicaSimulink package (which provides functionality similar to MATLAB’s Simulink for visualization), you can use a Modelica.Thermal.HeatTransfer.Blocks.Display block.
Here is an example of how you might achieve this in Modelica:
model HelloWorld
Modelica.Thermal.HeatTransfer.Blocks.Display text("Hello World!") annotation(
Placement({0, 0})
);
end HelloWorld;
In a real-world application, the Display block would be used to show information during simulation, but it is not intended for actual “print” or “output” commands. The placement and visibility can be adjusted as needed.
If you want to use this in a more graphical interface like ModelicaSimulink, the exact steps might vary depending on the tool you are using.
