Model: Notation – MOSAICmodeling

On this page

A notation is the basic nomenclature of any system or subsystem inside MOSAICmodeling. Complex equation systems or models may have several connected notations. However, let us begin with a single notation here. The more complex case of several notations will be discused in the section on connectors.

Purpose of the notation

Every variable element that you use in your equations, must be introduced in a notation. This shall inform the choice of your variable names and makes sure that you think about the names of each variable. A variable inside MOSAICmodeling may consist of up to four different parts:

Base names
Superscripts
Subscripts
Indices

Each variable may only have one Base Name and one Subscript, but as many Superscripts and Indices as required:

$\mathrm{Base}_{\mathrm{subscript}, \mathrm{index}_1, \mathrm{index}_2, \dots}^{\mathrm{superscript}_1, \mathrm{superscript}_2, \dots}$

Base Names, Superscripts, Subscripts, and Indices for all variables appearing within your Equation System need to be entered into your Notation with the help of the Notation editor (Figure 1).

Figure 1: The Notation editor inside MOSAICmodeling lets you enter base names, superscripts, subscripts, and Indices describing your model. Engineering Units can be preassigned to Variable Names optionally. Note that this editor might look differently depending on your operating system.

Explanation of the notation editor

Table 1 explains the entries of the notation editor.

Element	Explanation
File	Filename of your notation once you have saved or loaded it
Unit set	Filename of your loaded unit set
Description	Description of your notation, e.g., its purpose system. A description is always necessary
Keywords	Optional keywords for your notation
Base names	All base names of your notation
Superscripts	All superscripts of your notation
Subscripts	All subscripts of your notation
Indices	All indices of your notation
Index (in adding window)	When you click on the plus at the bottom right corner, and adding window opens. Here you need to add the index (or the another variable element)
Max. value (in adding window)	In the case of an index, you need to set the variable that determines the maximum value of this index so that you can, for example, in sum formulation
Description (in adding window)	A short description of the index, e.g., “component index”
