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.
