Buildings.Utilities.Diagnostics

Library with models to diagnose model errors

Information

This package contains components models for run-time diagnostics. The models in this package can be used to stop a simulation if a test is violated.

Extends from Modelica.Icons.VariantsPackage (Icon for package containing variants).

Buildings.Utilities.Diagnostics.AssertEquality Buildings.Utilities.Diagnostics.AssertEquality

Assert when condition is violated

Buildings.Utilities.Diagnostics.AssertEquality

Information

Model that triggers an assert if |u1-u2| > threShold and t > t0.

Extends from BaseClasses.PartialInputCheck (Assert when condition is violated).

Parameters

TypeNameDefaultDescription
TimestartTime0Start time for activating the assert [s]
RealthreShold1E-2Threshold for equality comparison
Stringmessage"Inputs differ by more than ... 

Connectors

TypeNameDescription
input RealInputu1Value to check
input RealInputu2Value to check

Modelica definition
