This opens the $Solver Access Window. The tab pages will change depending on if this is a Steady State (ProBal) or Dynamic project.
Steady State Solver Settings
For Steady State Projects, the following Tabs are available:
FS_Solver | ProBal | Convergence | GlobalTear | Tears | TearTags | Tolerances | Analysis |
---|
Brief Summary:
- FS_Solver Tab: For Threading and solver related command buttons.
- Probal Tab: For setting solver start actions and closure tolerances.
- Convergence: Displays the current convergence information.
- GlobalTear: For defining Global Tear convergence method, tolerance settings.
- Tears: Displays individual tear states, include current value and individual tear settings.
- TearTags: Displays a list of Tear tags, showing the associated unit models.
- TearStats: Displays individual tear counters and statistics.
- Tolerances: Displays the tolerances for system and model solvers.
- Analysis: For debugging purpose, used to narrow down problem areas of the project.
Dynamic Solver Settings
For Dynamic Projects, the following Tabs are available:
FS_Solver | Dynamic | Method | Scenario | Spills | Vents | SS Monitor | SS Finder | Convergence | GlobalTear | Tears | TearTags | Tolerances |
---|
Brief Summary:
- FS_Solver Tab: For Threading and solver related command buttons.
- Dynamic Tab: For simulation time information and Loading of a Historian tag list (for one trend page)
- Method: For setting step size, solver method, network convergence and tolerance settings.
- Scenario: For defining scenario, including run duration, start up options and so on.
- Spills: For capturing spillage during the simulation.
- Vents: For capturing gas venting from Tank (if a vent stream is not connected).
- SS Monitor: Mainly used for monitoring projects that are set to run to steady state. User can defined convergence criteria to determine if the project has reached steady state.
- SS Finder: User can set some criteria for the checking of Temperature, Pressure, Mass and MassFlow change in the project.
- Convergence: Displays the current convergence information.
- GlobalTear: For defining Global Tear convergence method, tolerance settings.
- Tears: Displays individual tear states, include current value and individual tear settings.
- TearTags: Displays a list of Tear tags, showing the associated unit models.
- TearStats: Displays individual tear counters and statistics.
- Tolerances: Displays the tolerances for system and model solvers.
