NullHeatTransferCoefficient¶
Overview¶
Data type
A null value for a physical quantity of type NullableHeatTransferCoefficient. The only instance of this singleton type is NULL_HEAT_TRANSFER_COEFFICIENT.
Supertypes
Implementation in Proteus Schema
All data attributes with type NullableHeatTransferCoefficient (the base type of NullHeatTransferCoefficient) are implemented as DEXPI generic attributes for physical quantities.
Example
Implementation in Proteus Schema
<GenericAttribute
Format="double" ...>
Note that the <GenericAttribute>
element must have a Name
and an AttributeURI
attribute. They depend on the data type attribute of the DEXPI class that owns the null instance NULL_HEAT_TRANSFER_COEFFICIENT (e.g., see the implementation example for the attribute DesignHeatTransferCoefficient of the DEXPI class HeatExchanger). For a null value, the attributes Units
, UnitsURI
, and Value
must not be used.
