Introduction

Command Button: SolverSettingsButton.png
The Command Path: View - Solver Settings
Alternate method: SysCAD background Right Click Popup Menu.

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 SS Monitor 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.
  • 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.
  • 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.
