Introduction

This tab page on the Plant Model Access Window has a number of parameters that the user may either set or read for Global settings. Most of the settings can also be made on the Audit page of any unit model.

Tag (Long/Short)	Input/Calc/Options	Description/Calculated Variables
AuditOptions (also see Audit)
Audit.On	Tickbox	Switch the Total Mass and Energy Audit calculations on or off. If off, no Total Audit calculations will be performed or displayed.
ElemAudit.On	Tickbox	Switch the Elemental Audit calculations on or off. If off, no Elemental Audit calculations will be performed. This option is for debugging and is always unticked on project load.
AuditCheck.MassTol.Rel	Display	Relative tolerance for mass balance checks.
AuditCheck.MassTol.Abs	Display	Absolute tolerance for mass balance checks.
AuditCheck.HeatTol.Rel	Display	Relative tolerance for energy (heat) balance checks.
AuditCheck.HeatTol.Abs	Display	Absolute tolerance for energy (heat) balance checks.
Frequency This setting determines when the Audit tests are performed.	EveryIteration	Only available in a steady state project. Audit calculations are carried out at every iteration.
	EveryStep	Only available in a dynamic project. Audit calculations are carried out at every step.
	WhenSolved	Only available in a steady state project. Audit calculations will only be carried out when the project is solved.
	WhenPausedOrSolved	Audit calculations will only be carried out when the solver is not busy, i.e. when the model is paused or stopped.
------ All Options Shown
Basics.ShowExtra	Tickbox	Show Extended Audit Details on the Audit tab.
Streams.Collect	Tickbox	Collect and show Streams Audit Summary table on the Audit tab.
Elements.Collect	Tickbox	Collect and show Elemental Audit Table on the AuditEl tab.
Elements.ShowExtra	Tickbox	Show additional columns in the Elemental Audit Table on the AuditEl tab.
Species.Collect	Tickbox	Collect and show Species Audit Table on the AuditSp tab.
Species.ShowExtra	Tickbox	Show additional columns in the Species Audit Table on the AuditSp tab.
Messages.OnError	Tickbox	Report audit errors to Messages Log in addition to Conditions window.
Pause.OnMassError	Tickbox	Pause model if a mass balance error occurs. This option is for debugging and is always unticked on project load.
Pause.OnElemMassError	Tickbox	Pause model if an elemental mass balance error occurs. This option is for debugging and is always unticked on project load.
Pause.OnHeatError	Tickbox	Pause model if a heat (energy) balance error occurs. This option is for debugging and is always unticked on project load.
Elements.DisplayTol.Rel	Input	Relative display tolerance for elemental mass imbalances.
Status - List worst tag and error Audit
