Model Types

About the Model Types

The Model Editor is where you create and modify Model Types representing process equipment, controls, and other mathematical relationships. You can create custom, company-specific Model Types that include proprietary Equations and save them to Model Libraries stored in the Repository. The Model Editor allows you to define variables and Equations in Model Types that represent chemical process models.

Concepts

• You can define new Model Types by using the Model Editor if no suitable model exists.

• You can modify an existing SimSci Model Type to make slight changes to fit your specific requirements.

• Model Types are stored in Model Libraries.

• You can build complex Model Types out of smaller Model Types by adding them as submodels.

• You can add model connections to a Model Type to reuse equations, variables, and parameters from one submodel across the model and its various submodels.

• Changes you make to a Model Type automatically propagate to all simulations that use the Model Type.

• Changes you make to a Model Type are automatically saved.

Actions

• Import an icon and associate it with a Model Type.

• Add variables based on Variable Types which define their units of measure.

• Define how variables are automatically specified for Process, Fluid Flow and Dynamics simulation Modes.

• Add equations that define mathematical relationships.

• Add a Model Type as a submodel to make more complex Model Types.

• Add a Port to a Model Type to define how the Model Type connects to other Model Types.

• Add time derivative equations so that you can model dynamic behavior.

• Add enumerated parameters and conditions to create optional or configurable Model Type behavior.

• Add model connections to reuse equations, variables, and parameters and thereby improve performance.

• Copy equations from one Model Type to another.
