public static class MEPCalculationFailures

The BuiltInFailures.MEPCalculationFailures type exposes the following members.

Properties

Name

Description


Public Property
Static Member

There should be at least one equipment on duty.


Public Property
Static Member

A calculation did not complete because the Classification parameter in the Mechanical Equipment family is not set.


Public Property
Static Member

A calculation did not complete because the Demand Flow for the element is not set.


Public Property
Static Member

Duct Fitting/Accessory Pressure Drop Calculator Not Available: [Calculator Name]


Public Property
Static Member

Duct Pressure Drop Calculator Not Available: [Calculator Name]


Public Property
Static Member

More than one parallel pump set defined for the same loop. Verify the flow distribution and delete the extra set, if desired.


Public Property
Static Member

During upgrade pressure drop calculations for hydronic piping systems using Simplified Colebrook or Custom Calculation methods have been recalculated using the Colebrook equation.


Public Property
Static Member

Unable to hydraulically separate until the system has flow.


Public Property
Static Member

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.


Public Property
Static Member

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.


Public Property
Static Member

The number of on duty equipment must be less than or equal to the number of available equipments.


Public Property
Static Member

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.


Public Property
Static Member

The mechanical equipment set was deleted because it no longer contained any members.


Public Property
Static Member

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.


Public Property
Static Member

The calculation could not be executed as configured. Specify a constraint property set for the following input or output node(s).


Public Property
Static Member

The calculation could not be executed as configured. Select an input node before analyzing this network.


Public Property
Static Member

The calculation could not be executed as configured. Select an output node before analyzing this network.


Public Property
Static Member

The calculation could not be executed as configured. Each network requires at least 1 pressure constraint. Specify the pressure constraint.


Public Property
Static Member

The calculation could not be executed as configured. Specify at least 3 elements before analyzing this network.


Public Property
Static Member

The calculation could not be executed as configured. Specify at least 4 elements before analyzing this network.


Public Property
Static Member

The network is not well connected. Some elements may have unexpected flow and pressure loss values.


Public Property
Static Member

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.


Public Property
Static Member

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.


Public Property
Static Member

The network uses the default pressure.


Public Property
Static Member

The network uses the default Reynolds number.


Public Property
Static Member

The energy calculation could not be performed.


Public Property
Static Member

The pressure calculation could not be performed.


Public Property
Static Member

The network needs an input or output element to perform the calculation.


Public Property
Static Member

The calculation could not be performed. Verify the pump curve data.


Public Property
Static Member

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.


Public Property
Static Member

The calculation could not be performed due to overconstrained flow condition in the network.


Public Property
Static Member

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.


Public Property
Static Member

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.


Public Property
Static Member

The minor loss calculation could not be performed.


Public Property
Static Member

The calculation could not be performed. Verify the pressure on the input element.


Public Property
Static Member

The network is under constrained. You may specify the design flow value in the missing branches, or cap the open ends.


Public Property
Static Member

A calculation did not complete because the connectors used by this family to connect to the network are not linked.


Public Property
Static Member

Pipe Fitting/Accessory Pressure Drop Calculator Not Available: [Calculator Name]


Public Property
Static Member

Pipe Pressure Drop Calculator Not Available: [Calculator Name]


Public Property
Static Member

Plumbing Flow Calculator Not Available: [Calculator Name]


Public Property
Static Member

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.


Public Property
Static Member

This hydraulic loop is not separated at any junction. Use the Remove Separation tool to clean up undesired hydraulic separations.


Public Property
Static Member

Hydraulic separation requires an even number of junctions on the header pipe for accurate calculations. Add or remove junctions to complete the separation.
