Gas Tracing Coarse-Grained Object

GasTraceHandler is the coarse-grained object for gas traces.

Gas Trace Options

There are no specific trace options for gas and water traces. You can use the generic trace options discussed on the Trace Options page or the options specific to the traces below.

Gas Valve Isolation Traces

These options are specific to gas valve isolation traces.

Trace Option	Default Value	Description
ExcludedValves	Empty int array	A set of valves that will not be used for analysis by the valve isolation traces.
GasWaterValveIsolationTraceBarriers	mmAllValves	Specifies whether only critical valves will be used for analysis by the valve isolation traces. Uses the mmGasWaterValveIsolationTraceBarriers enumeration.
IncludedValves	Empty int array	A set of valves that will be used for analysis by the valve isolation traces (even if these valves would not otherwise be used). This option is only valid for the critical valves gas trace options.
SqueezeOffs	Empty int array	Indicates the points on the pipe that were pinched and are closed for the flow of gas.
TemporarySources	Empty int array	The points on pipes to which temporary sources are attached.

Gas Pressure System Traces

These options are specific to gas pressure system traces.

Trace Option	Default Value	Description
PressureSystemTraceBarriers	mmGasPressureSystemTraceBarriers. mmAllRegulators	Specifies whether all regulators or only regulators with different in and out pressures will be used for analysis by the pressure system traces.

Gas System Traces

These options are specific to gas system traces.

Trace Option	Default Value	Description
GasSystemTraceBarriers	mmGasSystemTraceBarriers. mmTownBorderStationsAndRegulators	Specifies whether town border stations, regulators or both are used for analysis by the system traces.
