Optional element
Parameters are an essential part of every model. In MOSAICmodeling, you can easily set up these parameters so that they are automatically recognized and appear in an extra tab in the Simulation: Specifications
Purpose
The purpose of parameter lists is to hold variables with constant values for both equations and functions. For example, the universal constant will always be a constant parameter in your models. Therefore, it makes sense to define it within the parameter list.
In addition, adjustable parameters of unit operations (e.g. for CAPE-OPEN) must be declared in a parameter list, too. Each parameter abides by the same rules as all other MOSAICmodeling variables, meaning that a base name may be joined by a single subscript, and several superscripts and indices.
Explanation of the editor
Parameters need to be added to your parameter list with the help of the editor in Figure 1. Table 1 explains the entries of the notation editor. Once you have added them via the “+” sign, they appear in the column “Variable Naming”. Optionally, their respective engineering unit can be selected.
| Element | Explanation |
|---|---|
| File | Filename of your parameter list once you have saved or loaded it |
| Notation | Notation on which your parameter list is based |
| Description | A description of the current parameter list |
| Keywords | Optional keywords for your notation |
| Usages | Model elements, i.e., equations or functions, in which the parameter list is used |
| Parameters | Parameters defined by you as they will appear in your equations |
| Entries on right side | The tabs “Base Names”, “Superscripts”, etc. show you the currently loaded notation so that you may see which symbols are already defined. You can only use symbols, indices, etc. for your parameters that appear in this list |
Workflow
