|
|
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.
