Buildings.Utilities.Diagnostics.AssertEquality

Information

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

Parameters

Type	Name	Default	Description
Time	startTime	0	Start time for activating the assert [s]
Real	threShold	1E-2	Threshold for equality comparison
String	message	"Inputs differ by more than ...

Connectors

Type	Name	Description
input RealInput	u1	Value to check, equal to 0 if unconnected
input RealInput	u2	Value to check, equal to 0 if unconnected
