Overview
SysCAD provides a Species Database used to define the thermodynamic and physical property data for chemical species within a project. These species may include elemental substances, defined compounds, and pseudo-components required for process modelling.
SysCAD is designed as a process simulation tool and focuses on providing robust modelling capabilities. It is not intended to be a provider of chemical species property data. As such, comprehensive thermodynamic and physical property data, particularly for specialised or less common compounds, is not supplied with the software.
Users are responsible for sourcing accurate property data from appropriate references, such as published literature, trusted databases, or experimental results, and entering this data into the Species Database. This ensures that the project database is tailored to the required level of accuracy and is appropriate for the specific application.
Compounds that are not available in the supplied databases must be created and defined manually by the user.
There are two Species Databases in SysCAD:
- Default.93.db3
- This is the distributed main database, located in the \SysCADxxx\Base files folder (see BaseFiles Folder).
- It contains a selection of commonly used chemical species for general purposes.
- Editing this database is not recommended, as it may be overwritten during SysCAD reinstallation or BaseFiles updates, resulting in loss of any user-defined modifications.
- SysCAD.93.db3
- This is the project-specific database, typically created per project or project group (see Project Structure).
- This database should contain all chemical species relevant to the project, including any user-defined compounds and associated property data.
Users can populate the project database by:
- mporting species from Default.93.db3
- Importing from other SysCAD project databases (SysCAD.93.db3)
- Importing from external SysCAD-format databases (e.g. NASA_Glenn_Gas.93.db3)
- Importing from legacy databases (see Importing Data)
Editing Species Database
Please see Editing User Species Database for how to edit the species database.
Please also see Species Tags for species naming rules.
Adding Species to the Project
Once the species data are defined in the species database, species can be added to the project by selecting them in the project configuration file. For more information on this, please see Species Configuration.
Implementation in SysCAD
- Species Table - the list of thermodynamic properties that can be defined in the species database are described here.
- Editing Species Database - this shows how to edit the species database.
- Viewing Species Properties in SysCAD - The species properties can be viewed in SysCAD at user defined conditions.
- Species Properties Reports - Individual species properties can be exported for analysis.
- Species Table Properties Reports - The Species Table can be exported for analysis.
