Draw a Circle with Parametric Plot

The Draw a Circle with Parametric Plot pattern creates elements and a diagram that models a Circle that can be used as the definition for a simulation using Open Modelica. The Constraints specify the mathematical equations that define the circle relating the variables defined as properties.

Figure 1. Shows a Block Definition diagram with a single Block defined representing the Circle.

Figure 2. Shows the Project Browser where the elements and diagrams are grouped together in a Package. The SysML Simulation Configuration Artifact can be opened allowing the equation to be solved and the simulation to be run.

Tools you may find useful
The following are some of the tools that will be helpful when working with this pattern.
Artifact
An Artifact can be used as a way of configuring the parameters used or the BPSim simulation  For more details see the Artifact help topic.
Specification View
The Specification View can be used as a way of working with any element type in a spreadsheet or word process view. It is particularly useful when there are a large number of elements as is typically the case when describing a system of any appreciable size. For more details see the Specification View help topic.
Relationship Matrix
The Relationship Matrix provides a spreadsheet like view of two groups of elements and the relationships that exist between them. It can be a used as a powerful analysis mechanism to visually indicate how elements are related to each other and to discover which elements are missing relationships. For more details see the Relationship Matrix  help topic.
Traceability Window
The Traceability Window automatically displays the relationships that exist between Use Cases and other model elements including up-process and down-process elements. The traceability tree view can be conveniently expanded to see deeper relationships and elements displayed in the window can be located in all diagrams in which they appear. For more details see the Traceability Window  help topic.
Document Generator
The Document Generator is a powerful facility in Enterprise Architect that allows a Database Engineer or other stakeholder to create high quality corporate or technical documentation directly from the model, suitable for internal or external audiences. For more details see the Documentation help topic or the more general topic on Model Publishing.
Image Manager
The Image Manager is a tool for managing images such as photos and screen shots and other pictures in a variety of formats. Often when observations are made an analyst will take one or more photos of a user in situ in their work environment. An analyst might also capture screen shots of the current applications the user is working with. All these digital assets can be imported into the Image Manager and then applied to elements in diagrams as an alternate image. Alternatively a picture contained in the Clipboard can be pasted directly into a diagram. For more details see the Image Manager help topic.
Model Simulator
Model Simulation brings your behavioral models to life with instant, real-time behavioral model execution. Coupled with tools to manage triggers, events, guards, effects, breakpoints and simulation variables, plus the ability to visually track execution at run-time, the Simulator is a powerful means of 'watching your behavioral models in action' and verifying their correctness. With Simulation you can explore and test the dynamic behavior of models.  For more details see the Model Simulation help topic.
Element Discussions
The Element Discussion facility is a fully featured collaboration tool allowing modelers and model viewers and reviewers to communicate with each other directly inside the repository. Modelers using the full client or occasional viewers using WebEA can both post and reply to discussions and communicate and engage in chat. For more details see the Element Discussions help topic.
Hand Drawn and Whiteboard Diagrams
The Hand Drawn and Whiteboard Mode are display options available for any diagram that changes a system-drawn diagram to appear as though it was drawn by hand and, optionally, hand drawn on a whiteboard. It is a powerful device to engage an audience by presenting the diagram in a rough and more immediate style giving the impression that it is just a sketch that can be changed. For more details see the Hand Drawn and Whiteboard Mode help topic.
Alternate Images for Diagram Elements
Most standard elements allow an alternate image to be defined for an element that will be used in place of the graphical notation for the element either on a selected diagram or as a default on all diagrams. For more details see the Using the Image Manager help topic.
Diagram Layout
The Diagram Layout tool allows you to layout an entire diagram, selected elements or sections of a diagram to make it more visually appealing or meaningful to a particular audience. There are a wide range of layout types to choose from and some types have filters that can be applied. For more details see the Diagram Layout help topic.
Pan and Zoom
The Pan and Zoom facility is one of the tools that can be used to navigate around a large diagram. Often the resolution of a diagram must be reduced to ensure it is wholly visible but by using the Pan and Zoom window you can leave the diagram at a readable resolution and pan around to areas of interest zooming in when necessary. For more details see the Pan and Zoom help topic.
Diagram Legends
The Diagram Legend facility is useful for manually or automatically changing the appearance of elements and connectors on a diagram. A legend can be added from the Common Toolbox and configured to codify the fill and line color and line thickness. This is a powerful way to add meaning and expression to a diagram and is particularly expressive when applied automatically based on element or connector properties. It can be used with a number of specialized diagrams such as roadmaps to create a powerful visualization.  For more details see the Diagram Legends help topic.
