BuiltInFailuresMEPCalculationFailures Class Members:

Name	Description
AtLeastOneEquipmentOnDuty	There should be at least one equipment on duty.
ClassificationNotSetInFamily	A calculation did not complete because the Classification parameter in the Mechanical Equipment family is not set.
DemandFlowNotSetInLossFamily	A calculation did not complete because the Demand Flow for the element is not set.
DuctFittingAndAccessoryPressureDropCalculatorNotAvailable	Duct Fitting/Accessory Pressure Drop Calculator Not Available: [Calculator Name]
DuctPressureDropCalculatorNotAvailable	Duct Pressure Drop Calculator Not Available: [Calculator Name]
ExtraPumpSet	More than one parallel pump set defined for the same loop. Verify the flow distribution and delete the extra set, if desired.
FlowAndPressureCalculationMethodHasBeenImproved	During upgrade pressure drop calculations for hydronic piping systems using Simplified Colebrook or Custom Calculation methods have been recalculated using the Colebrook equation.
HydraulicSeparationAmbiguity	Unable to hydraulically separate until the system has flow.
HydraulicSeparationOfOneSystem	Unable to hydraulically separate the loop when both supply and return are assigned to the same system. Try again with both start and end selected.
InvalidFluidProperty	Some network components may have a flow value of 0 (zero), due to invalid value settings for fluid Dynamic Viscosity or Density. \nVerify that you have selected the correct fluid type and that the fluid Dynamic Viscosity and Density values are set correctly in the Mechanical Settings dialog.
InvalidNumberOfMechanicalEquipmentOnDuty	The number of on duty equipment must be less than or equal to the number of available equipments.
LoopSeparationNotCompleted	The loop separation is not completed yet. Only one side of the secondary/tertiary loop is separated. In order to correctly calculate the flow and pressure loss, please check and separate the other end of the loop.
MechanicalEquipmentSetBeingDeleted	The mechanical equipment set was deleted because it no longer contained any members.
Network_ElementNodeIsNotPartOfNetwork	The calculation could not be executed as configured. At least one of the elements in this network uses a node that is not part of the network.
Network_NodePropertyNotSet	The calculation could not be executed as configured. Specify a constraint property set for the following input or output node(s).
Network_NoInputNode	The calculation could not be executed as configured. Select an input node before analyzing this network.
Network_NoOutputNode	The calculation could not be executed as configured. Select an output node before analyzing this network.
Network_NoPressureConstraint	The calculation could not be executed as configured. Each network requires at least 1 pressure constraint. Specify the pressure constraint.
Network_NotEnoughElements	The calculation could not be executed as configured. Specify at least 3 elements before analyzing this network.
Network_NotEnoughNodes	The calculation could not be executed as configured. Specify at least 4 elements before analyzing this network.
Network_NotFullyConnected	The network is not well connected. Some elements may have unexpected flow and pressure loss values.
Network_OverConstrained	The calculation could not be executed as configured. The Pressure and Flow Rate combined constraint requires at least 2 other pressure or flow constraints. Specify additional constraints.
NetworkCanNotDeterminCriticalPath	The calculation has completed, but there may be an error in determining the critical path. Verify that demand flow is specified for all required elements.
NetworkDefaultToPressure	The network uses the default pressure.
NetworkDefaultToReynolds	The network uses the default Reynolds number.
NetworkEnergyEquationNotConverge	The energy calculation could not be performed.
NetworkErrorCalculatingPressure	The pressure calculation could not be performed.
NetworkErrorElementWithDownUpStreamNode	The network needs an input or output element to perform the calculation.
NetworkErrorExtractCurveData	The calculation could not be performed. Verify the pump curve data.
NetworkErrorModelTooBig	The size of the network exceeds the current limit for flow/pressure analysis. In the Mechanical Settings dialog, under Pipe Settings - Calculation, disable the option to Use analysis for closed loop hydronic networks.
NetworkErrorOverConstrained	The calculation could not be performed due to overconstrained flow condition in the network.
NetworkExtraPumpOutsideSet	Flow calculations do not calculate this pump together with the other pumps as one equipment set. Verify the flow distribution and add the pump to the equipment set, if desired.
NetworkInconsistentDemandFlow	The specified flow on this equipment is inconsistent with the other equipment in this branch. The branch flow is calculated based on the maximum specified value.
NetworkMinorLossNotConverge	The minor loss calculation could not be performed.
NetworkPressureNotConverge	The calculation could not be performed. Verify the pressure on the input element.
NetworkUnderConstrained	The network is under constrained. You may specify the design flow value in the missing branches, or cap the open ends.
PipeConnectorsAreNotLined	A calculation did not complete because the connectors used by this family to connect to the network are not linked.
PipeFittingAndAccessoryPressureDropCalculatorNotAvailable	Pipe Fitting/Accessory Pressure Drop Calculator Not Available: [Calculator Name]
PipePressureDropCalculatorNotAvailable	Pipe Pressure Drop Calculator Not Available: [Calculator Name]
PlumbingFlowCalculatorNotAvailable	Plumbing Flow Calculator Not Available: [Calculator Name]
PumpPressureNotComputed	The calculated pressure drop of this pump is not computed because the critical path is not a closed loop. Check to see if there are other pumps intended for use within a secondary/tertiary loop. Use the Add Separation tool to define the secondary/tertiary loop.
SeparationNotAtJunction	This hydraulic loop is not separated at any junction. Use the Remove Separation tool to clean up undesired hydraulic separations.
SeparationWithOddJunction	Hydraulic separation requires an even number of junctions on the header pipe for accurate calculations. Add or remove junctions to complete the separation.
