Provides a container of all Revit built-in FailureDefinitionId instances.
The BuiltInFailures MEPCalculationFailures type exposes the following members.
Properties
| 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. |
| | DemandFlowAndPressureLossNotSetInLossFamily | A calculation did not complete because the pressure loss value for element is not set. Select the element and enter a value for the Pressure Loss. |
| | 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. |
| | 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] |
| | PressureLossNotSetInLossFamily | A calculation did not complete because the pressure loss value for the source equipment is not set for the network. |
| | 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. |
