How do I add a graphical input in my model?
How do I add a graphical input in my model?

Hi!
I trying to build my own library in OpenModelica. It going to be a hydraulic library. Right know I have build a tank, but no signal cannot connect to it as you see.
My code for this tank is:
Code:
model Tank
parameter EasyHydraulics.Setup.PressureUnit P;
EasyHydraulics.Setup.Connecter C;
annotation(
Diagram(graphics = {Rectangle(origin = {-53, -12}, fillColor = {0, 0, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-7, 32}, {13, -48}}), Rectangle(origin = {0, -49}, fillColor = {0, 8, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-40, 9}, {40, -11}}), Rectangle(origin = {50, -21}, fillColor = {8, 15, 251}, fillPattern = FillPattern.VerticalCylinder, extent = {{10, -39}, {-10, 41}}), Rectangle(origin = {0, 20}, fillColor = {1, 6, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-10, 40}, {10, -22}})}, coordinateSystem(initialScale = 0.1)),
Icon(graphics = {Rectangle(origin = {-53, -12}, fillColor = {0, 0, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-7, 32}, {13, -48}}), Rectangle(origin = {0, -49}, fillColor = {0, 8, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-40, 9}, {40, -11}}), Rectangle(origin = {50, -21}, fillColor = {8, 15, 251}, fillPattern = FillPattern.VerticalCylinder, extent = {{10, -39}, {-10, 41}}), Rectangle(origin = {0, 20}, fillColor = {1, 6, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-10, 40}, {10, -22}})}, coordinateSystem(initialScale = 0.1)));
end Tank;
If I insert this code
Code:
Modelica.Mechanics.Rotational.Interfaces.Flange_a flange_a
annotation (Placement(transformation(extent={{-110,-10},{-90,10}})));
So it would look like this:
Code:
model Tank
parameter EasyHydraulics.Setup.PressureUnit P;
EasyHydraulics.Setup.Connecter C;
Modelica.Mechanics.Rotational.Interfaces.Flange_a flange_a
annotation (Placement(transformation(extent={{-110,-10},{-90,10}})));
annotation(
Diagram(graphics = {Rectangle(origin = {-53, -12}, fillColor = {0, 0, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-7, 32}, {13, -48}}), Rectangle(origin = {0, -49}, fillColor = {0, 8, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-40, 9}, {40, -11}}), Rectangle(origin = {50, -21}, fillColor = {8, 15, 251}, fillPattern = FillPattern.VerticalCylinder, extent = {{10, -39}, {-10, 41}}), Rectangle(origin = {0, 20}, fillColor = {1, 6, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-10, 40}, {10, -22}})}, coordinateSystem(initialScale = 0.1)),
Icon(graphics = {Rectangle(origin = {-53, -12}, fillColor = {0, 0, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-7, 32}, {13, -48}}), Rectangle(origin = {0, -49}, fillColor = {0, 8, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-40, 9}, {40, -11}}), Rectangle(origin = {50, -21}, fillColor = {8, 15, 251}, fillPattern = FillPattern.VerticalCylinder, extent = {{10, -39}, {-10, 41}}), Rectangle(origin = {0, 20}, fillColor = {1, 6, 255}, fillPattern = FillPattern.VerticalCylinder, extent = {{-10, 40}, {10, -22}})}, coordinateSystem(initialScale = 0.1)));
end Tank;
The tank will look like this then:
So my question is: How do I insert a graphical input so it can be connected to a variable?
I have attached my library.
EasyHydraulics.mo
The reason why I'm writing a library is to learn both hydraulics and programming with modelica.

Thank you

Hi!
your Connector in the tank model is missing an annotation. If you drag the connector Connecter from the library into the tank model then you can use it as desired.
You can add the input from the connector to a variable like this:
Code:
EasyHydraulics.Setup.Connecter C
Modelica.SIunits.Pressure P;
equation
P = C.P;

Thanks! It working now.
